The last week of October (2019) was very busy for me with planed and unplanned events that I photographed. </div>
<div style="direction: ltr; text-align: left;">
On Saturday evening (26th) there was a thunderstorm a bit from me so most of the lightnings were far. and yet some were very close like this one.<br />
<br />
There are several methods to capture lightnings. One way is to put a camera on tripod and set it for long exposures of 5 seconds, hoping to catch something. If the storm is heavy you can try and take a video, even with your smartphone, using the slow motion option, which works better than regular video even that it has a limited duration.</div>

On Sunday I noticed lightnings in a very far cloud (70 km from me). It was very strange to see these far away lightnings within the cloud as can be seen in this short movie.<br />

Tuesday (29th) was the first option to see the new moon. Stating with a nice sunset, I spot the moon, and as a bonus Venus and Mercury were close as well.</div>
<div style="text-align: left;">
In the photo with all three it is clearly seen that while Venus is more or less on the ecliptic, The moon is norther and Mercury is to the south.</div>

It is important to understand that in such case it is extremely important to be near he central line as possible. Even few kilometers east or west of it and the flare will not be visible. during the night one can be tens of kilometers away but not during the day.<br />
<br />
I choose a spot on the central line and setup my camera using the smart phone compass, and about 20<br />
seconds before the pass start to record a video.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<iframe allowfullscreen='allowfullscreen' webkitallowfullscreen='webkitallowfullscreen' mozallowfullscreen='mozallowfullscreen' width='320' height='266' src='https://www.blogger.com/video.g?token=AD6v5dwEOZo5GoO3OFEkUjFZeBn8nVlMujTR6nTSuwIT_xB0ZvXkRwJo0dhdhMJD0a07zSq-_T6KSnoxhjFzN4Ymqw' class='b-hbp-video b-uploaded' frameborder='0'></iframe></div>
<br />
<br />
The flare was very bright and very short, and the final result is seen in the photo at the beginning of the post.<br />
The camera is much more sensitive than the human eye, and recorded some seconds of the flare but<br />
unfortunately I didn't aim it to the correct spot.<br />
<br />
So what went wrong? I wanted to use a larger focal length to capture a long and wide flare. using longer focal length require precision so it is better to use lower focal length. Also since the flare moves from top to bottom (or bottom to top), putting the camera vertically will give mush more space for errors. So more is less. More zoom, less space for errors, and I should use 50mm instead of 70mm.<br />
<br />
To summarize here is an old video showing rare double daytime Iridium! At least I got that right!<br />
<br />
And to finish the post, we will add a great sunset photo after the flare<br />

Beresheet, the first Israeli spaceship to the moon, after 42 days in space, completed a critical maneuver and now orbiting the moon and not the Earth.<br />
<br />
5/4/2019- First photo of the moon<br />
After examining the preliminary data received during the night from Beresheet by the engineering team of SpaceIL and IAI, the control room updates that Beresheet is in an excellent orbit!<br />
The nearest point to the moon (Perilune) is 470 km from the moon and the point farthest from the moon (Apolune) at a distance of 10,400 km.<br />
The landing is scheduled for April 11 approximately 23:00 Israeli time - an accurate update will be published in the coming days. During the coming week, the maneuvers intense preparations for the landing will be conducted.<br />
Yesterday during the critical Lunar Capture maneuver, "Beresheet" photographed amazing photos of the moon while activating the engines.<br />

<br /><br />YEHUD, Israel, April 4 – SpaceIL’s engineering team and Israel Aerospace Industries (IAI) this evening at 5:17 p.m. Israel team conducted the most critical maneuver to date of Beresheet’s journey to the moon – the Lunar Capture. This maneuver enabled the spacecraft to be captured by the moon’s gravity and begin orbiting the moon – and with the moon, orbiting the Earth.<br /><br />Today’s maneuver moved the spacecraft into an elliptical orbit around the moon, with the closest point (perilune) 500 km to the moon, with the farthest point (apolune) 10,000 km from the moon. Unlike the longer orbits around the Earth, Beresheet’s first lunar orbit will last 14 hours. Before it lands on the moon, each orbit thereafter will take only two hours. At the beginning of this week, Beresheet reached, for the last time, the closest point to Earth in its last Earth orbit, only 1,700 km, and continued on course to the point where it could join the lunar orbit, 400,000 km from Earth.<br /><br />At 5:18 p.m. Israel time the spacecraft’s engine activated for six minutes, and reduced its speed by 1,000 km/hour, from 8,500 km/hour to 7,500 km/hour, relative to the moon’s velocity. The maneuver was conducted with full communication between Beresheet’s control room in Israel and the spacecraft, and signals in real time match the correct course. In the coming week, with expected intense engineering activities, many more maneuvers will take Beresheet from an elliptical to a round orbit, at a height of 200 km from the moon. The maneuvers will aim to reduce the spacecraft’s distance from the moon and reach the optimal point to conduct an autonomic landing in the Sea of Serenity in the evening Israel time, April 11.<br /><br />SpaceIL Chairman, Morris Kahn: “The lunar capture is an historic event in and of itself – but it also joins Israel in a seven-nation club that has entered the moon’s orbit. A week from today we’ll make more history by landing on the moon, joining three super powers who have done so. Today I am proud to be an Israeli.”<br /><br />SpaceIL CEO, Ido Anteby: “After six weeks in space, we have succeeded in overcoming another critical stage by entering the moon’s gravity. This is another significant achievement our engineering team achieved while demonstrating determination and creativity in finding solutions to unexpected challenges. We still have a long way until the lunar landing, but I‘m convinced our team will complete the mission to land the first Israeli spacecraft on the moon, making us all proud.”<br /><br />IAI CEO, Nimrod Sheffer: “After a challenging journey, we made tonight another Israeli record and became the seventh nation to orbit the moon. Even before Beresheet was launched, it already was a national success story that shows our groundbreaking technological capabilities. Tonight, we again reach new heights. In the coming week, our talented engineering team will work 24/7 to bring us to an historic event on April 11. Good luck Beresheet.”<br /><br /><br /><div class="MsoNormal" style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; text-align: justify;">

SpaceIL is a non-profit organization established in 2011 aiming to land the first Israeli spacecraft on the moon. SpaceIL was founded by three young engineers competing for the international Google Lunar XPRIZE challenge to build, launch and land an unmanned lunar spacecraft. SpaceIL’s other stated goal is to inspire the next generation in Israel and around the world to choose to study science, technology, engineering and mathematics (STEM).</div>
<br />
If you visited Israel in the last years you probably saw a small model of Beresheet in the airport, asking for people to do selfie with the model. Some of the photos will go to the moon, maybe even mine.<br />

The spacecraft's journey to the Moon - Once launched, the spacecraft will begin with a long and complex flight. The spacecraft will disengage from the SpaceX launch rocket when it reaches 60,000 kilometers from Earth’s surface and begin orbiting the Earth in elliptic orbits. It will circle Earth, widening its circumference each time, while saving fuel and only starting the engines at the end of each cycle. Then, at the right time, it will leave Earth’s gravity and enter the gravity of the moon. After circling the moon a few times, it will begin the landing process, carried out autonomously by the spacecraft's navigation control system. The entire flight, from launch through landing, will take about two months.</div>
<div>
<br /></div>
<div>
<b>The mission </b>- Once the spacecraft, carrying the Israeli flag, lands on the moon in April 2019, it will begin taking photos of the landing site. It will also perform measurements of the magnetic field in a scientific experiment carried out in cooperation with the Weizmann Institute and NASA. The data collected from this experiment will be transferred to IAI's control room during the two days following the landing.</div>

Now, Israeli nonprofit SpaceIL and Israel Aerospace Industries (IAI) presented today at IAI’s Space Division a time capsule that will travel to the moon — and remain there indefinitely — with the first Israeli spacecraft, which will launch from Cape Canaveral, Florida, in February, 2019.</div>
<div>
<br /></div>
<div>
<b>The time capsule</b> consists of three discs, each containing hundreds of digital files. Included among the files, which will travel to the moon inside SpaceIL’s lunar spacecraft, are: Details about the spacecraft and the crew building it; national symbols, like Israel’s Declaration of Independence, the Bible, Israel’s national anthem, “Hatikvah”, and the Israeli flag; cultural objects; materials – paintings, for example – collected over many years from the public for sending to the moon; dictionaries in 27 languages and encyclopedias, such as Wikipedia, an indication of knowledge accumulated by all humanity thus far; Israeli songs; the Wayfarer’s Prayer; books of art and science and Israeli literature; information about Israeli scientific and technological discoveries and developments that influenced the world; photos Israel’s landscapes and of leading figures in Israeli culture; a children’s book that was inspired by SpaceIL’s mission to the moon.</div>

The time capsule, along with the spacecraft, will remain on the Moon indefinitely, even after completing Israel’s first lunar mission. With no plans to return to Earth, the spacecraft and information within the time capsule’s disks will possibly be found and distributed by future generations.</div>
<div>
</div>
<div>
In early 2019, the spacecraft, recently named Beresheet (the Hebrew word for Genesis), will launch alongside other satellites as a secondary payload on a SpaceX Falcon 9 rocket. The precise launch date remains undetermined, as SpaceIL awaits final confirmation from the launch company.</div>

"This is another step on our way to the moon," said Ido Anteby, CEO of SpaceIL. “Inserting the disks into the spacecraft, which is a real "time capsule," indicates the spacecraft's readiness to blast off from the launch site in a few weeks. SpaceIL's crews and IAI have completed testing of the spacecraft and its systems, and are preparing for the beginning of the amazing and complex journey that exemplifies innovation, creativity and courage. The spacecraft's historic journey, which also includes a scientific mission, makes a significant contribution to advancing the space industry and the subject of space in Israel."</div>

Yonatan Winetraub, one of three SpaceIL founders, said, as he inserted the time capsule into a spacecraft: "This is a very emotional moment. We do not know how long the spacecraft and the time capsule will remain on the moon. It is very possible that future generations will find this information and want to learn more about this historic moment."</div>
<div>

<br />
Here is a short video showing the insertion of the time capsule:<br />

Opher Doron, IAI’s Space Division General Manager, said: "We are proud to be the first non-governmental entity in the world to go to the moon. Landing on the moon was for many years a little-discussed topic among the public, but recently we see growing interest as world superpowers seek to return to the moon in a variety of commercial missions. There is no doubt that the technological knowledge acquired by IAI during the development and construction of Beresheet, together with Space IL and combined with the space capabilities developed over more than 30 years at IAI, puts us at the global forefront in the ability to complete lunar missions."</div>
<div>
<br /></div>
<div>
The spacecraft, whose construction was carried out at IAI’s Space Division, successfully completed a series of recent tests to examine the integration of systems, and a series of complex experiments aimed at testing its durability. Concurrently, validation and verification tests checked the function of the spacecraft in scenarios it could experience during the mission. Since actual space conditions cannot be replicated, tests are carried out in part by a SpaceIL simulator that mimics space conditions and part on the spacecraft itself. Next, SpaceIL will soon ship the spacecraft to the launch site in Cape Canaveral, Florida.</div>
<div>
<br /></div>
<div>
In October, SpaceIL and the Israeli Space Agency announced a collaboration with NASA that will enable SpaceIL to improve its ability to track and communicate with the spacecraft before, during, and after landing on the moon. Two weeks ago a retro-reflector from NASA was installed on the spacecraft, an instrument that reflects laser beams and will enable NASA to precisely locate the spacecraft on the lunar surface after the landing. SpaceIL, the Israel Space Agency and NASA also agreed that NASA will have access to data gathered by the magnetometer installed aboard the Israeli spacecraft. The instrument, which was developed in collaboration with Israel’s Weizmann Institute of Science, will measure the magnetic field on and above the landing site.</div>
<div>
<br /></div>
<div>
Please find below photos from today’s event at IAI’s Space Division and examples of photos the will be included in the time capsule.</div>
<div>
<br /></div>
<div>
The launch will take place on a SpaceX rocket in first quarter of 2019, and the Moon landing will be at the end of a two-month journey in space. Since the establishment of SpaceIL, the task of landing an Israeli spacecraft on the moon has become a national project, with educational impact, funded by donors such as Dr. Miriam and Sheldon Adelson, Sami Sagol, Lynn Schusterman, Steven and Nancy Grand, Sylvan Adams and others. Morris Kahn, a philanthropist and businessman, took the lead in completing the mission, financing about NIS 100 million of the project and serving as SpaceIL’s president.</div>

<div dir="ltr" style="text-align: left;">
Although I don't care too much about <a href="http://www.thevenustransit.com/2012/05/supermoon.html">supermoons</a>, I always like to see the <a href="http://www.thevenustransit.com/2012/01/raising-moon.html" target="_blank">full moon rising</a> and this evening just 17 minutes after sunset I had a chance to see and take some photos.</div>
<div dir="ltr" style="text-align: left;">
<br /></div>

There are also a number of small changes to streamline recovery and re-usability of first-stage boosters. Alterations to the launch vehicle are primarily focused on increasing the speed of production and efficiency of re-usability. SpaceX aims to fly each Block 5 first stage ten times with only inspections in between, and up to 100 times with refurbishment.</div>

<div dir="ltr" style="text-align: left;">
A camera can be a small telescope. It collects lights, it has a larger aperture than your eye. A lens is a </div>
<div dir="ltr" style="text-align: left;">
lens.</div>
<div dir="ltr" style="text-align: left;">
<br /></div>
<div dir="ltr" style="text-align: left;">
As I wrote in a previous article: <a href="http://www.thevenustransit.com/2014/05/how-to-photograph-stars-and.html">How to photograph stars and constellations</a>, you can use any camera to photograph the sky. You should be realistic and understand that you are photographing mostly wide-filed photos. Entire constellations or large objects with a telephoto lens. The photos will help you see more stars, observe their different colors, and even to find deep sky objects such as clusters, nebulas and even galaxies.<br />
<br />
A DSLR is recommended and the better your lens the better the results but even with a compact camera it is possible to get nice results.</div>
<div dir="ltr" style="text-align: left;">
<br /></div>
<div dir="ltr" style="text-align: left;">
Photos can be taken from anywhere but to avoid light pollution it is best to go to darkest as possible places. No need to mention that a sturdy tripod is a must.</div>
<div dir="ltr" style="text-align: left;">
<br /></div>
<div dir="ltr" style="text-align: left;">
The major problem of photographing stars is that the earth rotate and the stars are smudged from dot to lines. You can use this rotation to produce great star trails photos but our aim in this specific article is to better see the stars and faint objects.<br />
<br />
The rule of thumb is that the longest exposure should not be more than 500/focal-length. For example, if you use a 28mm lens you can expose for 18 seconds without noticing much smudging. These number is correct for Full-Frame cameras. If you are using an APS camera, you should adjust by the crop factor (mostly 1.5) so 18 seconds becomes just 12. If you are using a telephoto lens you will have shorter exposures time.</div>
<div dir="ltr" style="text-align: left;">
<br /></div>
<div dir="ltr" style="text-align: left;">
So what to do? Use higher ISO, 400 800 or even 1600 depends on your specific model and open the aperture as possible.<br />
<br /></div>
<div dir="ltr" style="text-align: left;">
Focusing is another important matter. Manual focusing is a must. Try to find a bright star and use LiveView to better focus. If you are not sure, check your photo after a single exposure, zoom into it and adjust the focus as needed.<br />
<br />
A release cable/remote is also necessary to prevent the shake caused by pressing the shutter. If you do not have a remote/release cable use the self-photo feature to add 2 seconds delay before each photograph.<br />
<br />
To save time I take the first photo with a very high ISO (3200 or 1600), short exposure and without noise reduction. After I set the composition as I like I use a lower ISO and the longest possible exposure. Usually, I use the built-in "log exposure noise reduction" but it can be done later in a software if you take one or two photos of the same exposure time with the lens cap on. </div>
<div dir="ltr" style="text-align: left;">
<br /></div>
<div dir="ltr" style="text-align: left;">
To take your photos to the next level you will need a tracker device. The tracker is pointed to the polar star (or to the relevant area in the southern hemisphere) and rotates in the opposite direction to the earth, thus eliminating the smudging and enables longer exposures. I am using the <a href="http://amzn.to/2lV5woo">Ioptron tracker</a>, if you are handy you can build your own device (look for instructions to build a "barn door tracker").</div>
<div dir="ltr" style="text-align: left;">
<br /></div>
<div dir="ltr" style="text-align: left;">
If you go for a tracker notice that there are models with additional small finderscope which will give you much better results and you should buy that model. also notice that some models have a 3/8" mount while most tripods have a 1/4" mount, so a small adapter might be required (It is very cheap adapter). </div>
<div dir="ltr" style="text-align: left;">
<br /></div>
<div dir="ltr" style="text-align: left;">
Using the tracker is simple you put it on a tripod, points it to the north star, use the finderscope for exact alignment (I use a small app for my smartphone to do this - <a href="https://play.google.com/store/apps/details?id=com.techhead.polarfinder">Polar scope finder</a>, there are also free apps for this purpose). Put the ball-head on the tracker (carefully, not to move the tracker) and point the camera to the area you want to photograph. From time to time check that the tracker still points to the correct place.</div>
<div dir="ltr" style="text-align: left;">
<br /></div>
<div dir="ltr" style="text-align: left;">
Here are some examples, all photos are 30second exposure. the Pleiades cluster - M45 - is a nice object for 300mm lens.</div>

Facts and photos!<div dir="ltr" style="text-align: left;" trbidi="on">
<br />
From time to time, you hear news about a big and bright moon that has not been seen in the last ten, twenty, or even a hundred years. Such moons have the nickname, "supermoon". Here are some facts and information about supermoons. All numbers and times relate to the supermoon of November 14,2016.<br />
<br />
<b>What is a supermoon?</b><br />
A supermoon is a term for a full moon that is near perigee. The perigee is the point in the moon's orbit that is closest to earth. The moon is full once a month and also at perigee once a month. From time to time, the moon is both full and near perigee around the same time and the result is a somewhat larger and brighter moon, a.k.a. "supermoon".<br />
<br />
<b>What will be the distance to the current supermoon?</b><br />
<div>
The closest distance to the moon varies each month and averages around 357,000 kilometers. The earth's distance from the current supermoon will be 356,511 kilometers (227,118 miles). This distance is the distance between the earth's and moon's <b>centers. </b>The exact times (UTC) are:</div>
<div>
<ul style="text-align: left;">
<li>Moon at Perigee 13:24 </li>
<li>Full Moon 15:54 </li>
<li>The moonrise varies for different locations.</li>
</ul>
<b>Is the change of the moon's size significant?</b><br />
The difference between a distant moon ( >400,000 km) and a close moon is indeed significant and can reach 40,000 km which are 14% of the distance. This difference has an impact on the apparent size of the moon and 14% is is the number you will probably see in the news; however, I think they should calculate the difference based on the average distance of the moon, which is just half of that. </div>
<div>
The best (and only) way to see that difference is to take two photos and compare them. See the image below for example:</div>
<div>
<br />
<a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi3CBK13hotvfO9rtQPgQ-r4DGEm_PMZ8ppxZHL58Hm2Z0xM_8L7q_SdcyxakQkj81z88HbXmYk0xpTRBCNlLnt2U5MEF8L8ZhNEGBB2pHtQlxJHZ9C7MW5w1xx92Hd0SKIDZA0XA1a6pGq/s1600/apogee-perigee+moon2.jpg"><img border="0" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi3CBK13hotvfO9rtQPgQ-r4DGEm_PMZ8ppxZHL58Hm2Z0xM_8L7q_SdcyxakQkj81z88HbXmYk0xpTRBCNlLnt2U5MEF8L8ZhNEGBB2pHtQlxJHZ9C7MW5w1xx92Hd0SKIDZA0XA1a6pGq/s400/apogee-perigee+moon2.jpg" /></a> <br />
<br />
<br />
<b>The smallest distance since 1948</b><br />
Headlines such as "Nearest moon since 1948" are factually correct but are meaningless. As mentioned above the distance is between the earth's and moon's centers. The distance of the moon to a specific observer on earth is different and changes throughout the night as the earth revolves. </div>
<div>
Since 1948, there have been many others supermoons, some of them only 100 km farther than this supermoon. But if an observer on earth sees the moon before or after the exact perigee, this 100 km is negligible to the change due to earth's rotation (which is 6300 km about the same as earth's radii, in just a few hours). Such small changes of 0.1% have no effect on the moon's apparent size. It might be that for a given observer in a given location, there was a nearer moon after 1948.<br />
<br />
<br />
<b>Why is the moon orange or particularly large when it rises?</b><br />
The red rising moon is due to the atmosphere and the big rising moon is an illusion. Read more about the <a href="http://www.thevenustransit.com/2012/01/raising-moon.html">large red moon</a> here. Both phenomena are not related to the moon being a supermoon.<br />
<br />
<b>Will I see any difference in the size of the moon?</b><br />
Probably not. If you go out and look at the full moon you, will see that it is very bright. Maybe you'll notice it is brighter than the previous evening's moon, but that is true for every full moon. To see a change in the moon's size, you will have to compare the moon to something. To what? It is more or less the same as the day before and certainly one can't recall how a very far away moon looked several months ago. If you want to compare the difference in the size of the apparent moon, you need patience. Take some pictures, wait patiently for seven months (When then the full moon will be distant) and then take more photos.<br />
<br />
<b>What about the brightness of the moon?</b><br />
The brightness of the moon is a whole new ball game. The moon's apparent size depends only on its distance, but the brightness depends on other factors as well. So if the news reports about the distance are at least credible to some extent,<b> the reports on the brightness are almost always completely wrong.</b><br />
<br />
<b>Explanation:</b><br />
The two most obvious factors that affect the brightness of the moon are the moon's distance from the earth and also the earth's distance from the sun. As the two of them are the smallest possible, the brightness increases. The earth is close to the sun at the beginning of January, which is part of the reasons why this November's supermoon arrived the news.<br />
<br />
<b>Are there more important factors to the brightness of the moon?</b><br />
Yes, there are more, and the most important of is the phase angle, which relates to the distance of the moon (in degrees) from the ecliptic. The farther the moon, the less bright it will be. For the current supermoon, the moon is more than 5 degrees from the ecliptic so it will not be so bright after all.<br />
<br />
<b>When will the moon be the brightest?</b><br />
Suppose we have a full moon at perigee (closest to earth), we assume that the earth is at perihelion (closest to the sun), and we assume that it is also just on the ecliptic. In this situation, the moon would be at its brightest. But under these conditions, we would be in the middle of a very deep lunar eclipse, which is a great event to observe, but the moon is not seen at all. For this reason, the moon has a theoretical maximum brightness limit, but that limit can never be observed.<br />
<br />
<b>When will be the brightest moon that can be observed?</b><br />
Think again about the conditions in the previous section. The only compromise that can be done is that the moon will not be full, but just a little before or after (a difference of few hours) which means that the moon is as close as possible to earth, the earth is as close as possible to the sun, and the moon is almost full. This is just before or after a full lunar eclipse.<br />
<br />
<b>When is the next lunar eclipse with these conditions?</b><br />
The last supermoon eclipse was January 9,2001, and the next time will be an eclipse on December 12, 2114. The brightest supermoon between 1800-2200 will be on January 3, 2151, when the earth is almost at perihelion. These dates are from the book, "More Astronomical Morsels" by Jean Meeus.<br />
<br />
<b>So what is all the fuss about?</b><br />
As usual, much ado about nothing. But if such news will make people go out and observe the moon, so be it. The full moon and especially the rising of the moon are always an experience. Take a look for yourself in the video attached!<br />

<br />
<b>What other things you recommend we observe?</b><br />
The moon is always interesting to observe. Even a small pair of binoculars will show many details on its surface, which change daily depending on the phase of the moon. Eclipses are always interesting, and conjunctions of the moon and planets or bright stars are interesting. Actually, one day after this supermoon, on November 15, 20161, <a href="http://www.thevenustransit.com/2016/03/aldebaran-occultation.html">the moon will cover the star Aldebaran</a> in Taurus. This occultation will be visible to observers in Southeast Asia.<br />

<li><a href="http://www.nextbigfuture.com/2016/11/china-successfully-launched-new-long.html" target="_blank">The new Long March 5 rocket launched successfully on Thursday.</a> The rocket could be used to support a Chinese space station and send an uncrewed mission to Mars.
The new Long March 5 rocket launched successfully from the Wenchang Space Launch Center. The rocket measures 187 feet, making it the largest produced by China. It can carry 25 tons of payload into low-Earth orbit. The rocket carried a satellite that will be used to test a variety of technologies, from observing space debris to electric propulsion.</li>
<li>On October 5th 2016, Ranga Dias and Isaac F. Silvera of Lyman Laboratory of Physics, Harvard University released the <a href="http://www.nextbigfuture.com/2016/11/co-discover-of-metallic-hydrogen-wrote.html" target="_blank">first experimental evidence that solid metallic hydrogen has been synthesized in the laboratory</a>.
It took 495 GPa pressure to create. The sample is being held in the cryostat in liquid nitrogen.
Atomic metallic hydrogen, if metastable at ambient pressure and temperature could be used as the most powerful chemical rocket fuel, as the atoms recombine to form molecular hydrogen. This light-weight high-energy density material would revolutionize rocketry, allowing single-stage rockets to enter orbit and chemically fueled rockets to explore our solar system. To transform solid molecular hydrogen to metallic hydrogen requires extreme high pressures.</li>

With increasing pressure we observe changes in the sample, going from transparent, to black, to a reflective metal, the latter studied at a pressure of 495 GPa. They have measured the reflectance as a function of wavelength in the visible spectrum finding values as high as 0.90 from the metallic hydrogen. They have fit the reflectance using a Drude free electron model to determine the plasma frequency of 30.1 eV at T= 5.5 K, with a corresponding electron carrier density of 6.7x10^23 particles/cm3 , consistent with theoretical estimates. The properties are those of a metal. Solid metallic hydrogen has been produced in the laboratory.
* they have made some metallic hydrogen and have it in a cryostat in liquid nitrogen
* they might leave it under pressure and let it warm to room temperature or they could keep it cold and release the pressure
* they are planning to test for high temperature superconductivity</span></span></li>

This telescope element of JWST includes the optical components and science instruments. After testing, the telescope will be affixed to a sunshield to prevent thermal heating and a spacecraft bus that contains the propulsion and communication systems to complete JWST. Launch is scheduled for October 2018.</span> </span></li>

<span style="background-color: none; font-family: "times" , "times new roman" , serif;">One of the most common of natures phenomena is the sunrise, watched by millions of people throughout history, always pretty and never boring. The Bible mentions sunrise many times and I included several appropriate verses throughout the article.</span><br />

<div dir="ltr" style="text-align: left;">
<span style="background-color: none;">During this time of year there is a small gap in the buildings surrounding me, which enables a clear view of the sunrise in the east. I cannot see the exact sunrise, as the Samaria mountains block the horizon, but I do manage to see a few minutes after it. The series of photos show how each day the sun moves southward (the movement is actually the Earth movement in its orbit).</span></div>

<span style="background-color: none;">The apparent movement of the sun in the sky is a combination of two movements: the Earth revolving around its axis is the daily motion of the sun in the sky from sunrise to sunset, and the yearly movement of Earth in its orbit around the sun causing small changes in the sun's location during the seasons. That small change is shown in the series above as every day the sunrise is in a slightly different place.</span></div>

<div dir="ltr" style="text-align: left;">
Oops, I did that again! After almost 19 months I was able to take again a video of the ISS passing the moon! (Here is the story of the first time I caught the <a href="http://www.thevenustransit.com/2014/12/the-iss-crosses-moon.html">ISS and the moon)</a>.</div>
<div dir="ltr" style="text-align: left;">
<br /></div>
<div dir="ltr" style="text-align: left;">
I am receiving alerts from <a class="" href="http://www.calsky.com/">calsky</a> site about satellites crossing the moon, but I usually ignore them since most of the time it is a very small satellite which requires telescopes and to find the exact place, but this alert was different.</div>
<div dir="ltr" style="text-align: left;">
<br /></div>
<div dir="ltr" style="text-align: left;">
What are the chances to see an ISS pass? Very high, it happens all the time. what are the chances that the ISS will cross the moon? I think that *somewhere* it also happens all the time. But what are the chances that the crossing will happen exactly at your house?? Ohm. Small, rather small.</div>
<div dir="ltr" style="text-align: left;">
But improbable things happens all the times and as I got the alert I checked the predictions (see the appendix) and saw that indeed all I need to do is to go outside to my roof.</div>
<div dir="ltr" style="text-align: left;">
<br /></div>
<div dir="ltr" style="text-align: left;">
Even the problematic hour 4:56am did not bother me. I decided for the best configuration for my equipment and made all setups I could the evening before. I set an alarm and went to sleep early.</div>
<div dir="ltr" style="text-align: left;">
<br /></div>
<div dir="ltr" style="text-align: left;">
Getting up at 4:15 the skies are full of clouds, ignored them and continue to setup the system. Clouds come and goes and there is plenty of time, so just hope for the best. I aligned the mount and put my 70mm doublet on it with Canon700d on video mode.</div>
<div dir="ltr" style="text-align: left;">
<br /></div>
<div dir="ltr" style="text-align: left;">
I use a Nikon 900P camera with a mighty zoom on a regular tripod without tracking and an old Canon SX30 for backup. Ten minutes before the pass and everything was entirely cloudy. Five minutes before the pass the sky was clear.</div>
<div dir="ltr" style="text-align: left;">
<br /></div>
<div dir="ltr" style="text-align: left;">
Waiting. Here it is! Above the moon and going down so quick. Fast. Press record here, here and here! make a last alignment for the non-tracked Nikon camera and wait.</div>
<div dir="ltr" style="text-align: left;">
<br /></div>
<div dir="ltr" style="text-align: left;">
I took a look at the eyefinder to see if it catches the ISS but saw nothing. I looked at the ISS and saw that it already passed the moon. Well maybe the predictions were no that accurate and it missed the moon in a degree that is possible, nothing to do about that. Turn off all recordings, take apart everything I can without making too much noise (5am in the morning) and check what happened on the computer.</div>
<div dir="ltr" style="text-align: left;">
<br /></div>
<div dir="ltr" style="text-align: left;">
Happily, I found out that all three cameras captured the ISS. Most of the pass was on the dark side of the moon and only a fraction of it on the lit side. Here are the results combined into a single view. Please look at it on full screen with HD resolution</div>
<div dir="ltr" style="text-align: left;">
<br /></div>
<div class="separator" style="clear: both; text-align: center;">
<iframe allowfullscreen="" class="YOUTUBE-iframe-video" data-thumbnail-src="https://i.ytimg.com/vi/f6X5hzc407w/0.jpg" frameborder="0" height="266" src="https://www.youtube.com/embed/f6X5hzc407w?feature=player_embedded" width="320"></iframe></div>
<div dir="ltr" style="text-align: left;">
<br /></div>
<div dir="ltr" style="text-align: left;">
<br /></div>
<div dir="ltr" style="text-align: left;">
I tried to extract a single image from the video but the ISS was too smudged. I think that The Nikon camera went back to its default 30fps and not to the 60fps I set it up before. Always check your setup again, even if you are too tired at 4am! The ISS is the white little line on the dark side of the moon.</div>

One problem of such videos/photos is that it is hard to practice. The duration of the pass is one second or less. My recommendations for the next time are:</div>
<div dir="ltr" style="text-align: left;">
</div>
<ol dir="ltr" style="text-align: left;">
<li>Take the highest FPS you can: 60 120 or even 240 (with iPhone aligned to the eyepiece)</li>
<li>Practice on a regular moon without the ISS</li>
<li>To freeze the ISS use 1/1600 shutter speed</li>
<li>If you have a DSLR with a high zoom lens, use burst mode and don't take video.</li>
<li>Have fun doing all of that! </li>

<div dir="ltr" style="text-align: left;">
Jupiter is the largest planet in the solar system, a gas giant of Hydrogen and Helium with some Ammonia in the upper beautiful clouds layer (and small amounts of other things). Juno spacecraft will arrive to Jupiter on the symbolic day of the 240th independence day of the USA and enter into an orbit around it. Here are some interesting facts about Jupiter.</div>

<b>Jupiter is massive</b></div>
<div dir="ltr" style="text-align: left;">
Jupiter is not only big, it is massive as well. You can say that the entire mass of the solar system is divided in the following way. 99% of the mass is the Sun, 2/3% of the mass belongs to Jupiter and all the rest is just 1/3% (This division is not scientifically accurate but is suitable enough for our needs). Jupiter mass is two times the mass of everything else in the solar system except the sun, and this mass influences the sun and cause it to wobble a little in its orbit. The barycenter of the sun-Jupiter system is well OUTSIDE the sun. </div>
<div dir="ltr" style="text-align: left;">
<br /></div>
<div dir="ltr" style="text-align: left;">
<b>Jupiter can't become a star</b></div>
<div dir="ltr" style="text-align: left;">
Although Jupiter is huge it is still far too little to become a star and it requires to add at least twenty times its own mass or even more to become so. Adding just little more mass, two-three times as its current mass, will not make Jupiter bigger but will make it denser, but not dense enough to start nuclear fission. </div>
<div dir="ltr" style="text-align: left;">
<br /></div>
<div dir="ltr" style="text-align: left;">
<b>You can see Jupiter in daylight</b></div>
<div dir="ltr" style="text-align: left;">
Jupiter is seen clearly from Earth. It is the brightest object in the sky after the sun, moon and Venus. Under best conditions, <a href="http://www.thevenustransit.com/2013/03/seeing-jupiter-in-daylight.html">Jupiter can be seen during the day</a>. It requires some practice but possible.</div>
<div dir="ltr" style="text-align: left;">
<br /></div>
<div dir="ltr" style="text-align: left;">
<b>Jupiter has lots of visitors</b></div>
<div dir="ltr" style="text-align: left;">
The first spacecrafts to visit Jupiter were the Pioneer missions in the early seventies followed by both Voyagers missions in 1979. It took some time for the next visitor, Ulysses in 1992 which was on her way to explore the sun poles and got to Jupiter in order to use its gravity to change orbit. Galileo in 1995 was the first spacecraft to orbit Jupiter for a long period and ended in a brave crash into its atmosphere. Cassini just said a quick hello in 2000 on her way to Saturn and New-Horizons also "stopped by" for a cup of coffee on her way to Pluto. Juno mission will be an interesting long mission around Jupiter.</div>
<br />
<div dir="ltr" style="text-align: left;">
<b>Jupiter protects us</b></div>
<div dir="ltr" style="text-align: left;">
The great mass of Jupiter helps to keep the solar system clean and remove hazards such as asteroids and comets from the inner solar system. Sometimes Jupiter fell asleep during his watch and the dinosaurs are still angry about him, but without Jupiter, things will be worse. Jupiter also gets the bullet for us from time to time. In 1994 Shoemaker-Levy comet crashed into Jupiter and left some scars on it for about a year. Not long ago an amateur astronomer got another small crash on video:<br />

<b>Jupiter is not alone</b></div>
<div dir="ltr" style="text-align: left;">
Jupiter has lots of company. 67 moons so far and probably plenty of smaller ones. Its four largest moons were discovered in 1609 by Galileo. The largest moons - Io, Europa, Ganymede, and Callisto - are bright enough to be seen by the naked eye, but Jupiter is too close to them and prevents that. Even a small binoculars will show the moons.</div>
<div dir="ltr" style="text-align: left;">
<br /></div>
<div dir="ltr" style="text-align: left;">
<b>It is best to keep some distance from Jupiter</b></div>
<div dir="ltr" style="text-align: left;">
Ask Io. A small moon and one that its planet has enormous influenza on its structure. Io is smaller than our moon and the distance from Jupiter's center to Io is around 400,000 km. To be so close to Jupiter is not a good idea. Strong gravitational forces cause earthquakes and volcanic activity and made Io look like... Like what actually?</div>

<b>Jupiter helped to measure the speed of light</b></div>
<div dir="ltr" style="text-align: left;">
The Danish astronomer Ole Romer noticed a difference between the predicted time and actual time of Io's (The cheese ball from above) eclipses behind Jupiter. His idea was that these difference derived from the changes in Earth-Jupiter distance and that the light has a speed. He gave a value of 220,000km/sec which is around 76% of the actual value, a really good approximation!</div>

<div dir="ltr" style="text-align: left;">
How to remove or at least reduce light pollution is a frequently asked question. The "Blur and Subtract" technique is a process which I use to reduce light-pollution on my astro-photography images. I live in an urban area and the skies are never black. Of course the best thing is to travel to a darker place, but most of the time that is not possible. I wanted to have a quick method to remove some of the light pollution without working too much on the computer. As it turned out this method provides very interesting results in both daylight and night photos.</div>
<div dir="ltr" style="text-align: left;">
<br /></div>
<div dir="ltr" style="text-align: left;">
The name of the technique "<b>Blur and Subtract</b>" speaks for itself and has three major steps:</div>
<div dir="ltr" style="text-align: left;">
</div>
<ol dir="ltr" style="text-align: left;">
<li>Take your desired photo (Photo 1)</li>
<li>Take the same photo but use manual focus to blur the image as much as possible (Photo 2)</li>
<li>Subtract (Photo 1 - Photo 2)</li>
</ol>
<div dir="ltr" style="text-align: left;">
<br />
That is all, but if you are not familiar with any photo processing software continue to the <a href="http://www.thevenustransit.com/2016/06/blur-and-subtract.html#anchortext">detailed tutorial</a> or watch this two minutes demonstration video.<br />
<br />
<div class="separator" style="clear: both; text-align: center;">
<iframe width="320" height="266" class="YOUTUBE-iframe-video" data-thumbnail-src="https://i.ytimg.com/vi/9yV3T4JXeKI/0.jpg" src="https://www.youtube.com/embed/9yV3T4JXeKI?feature=player_embedded" frameborder="0" allowfullscreen></iframe></div>
<br />
<b><span style="font-size: large;">Why the "Blur and Subtract" method reduces light pollution?</span></b><br />
<br />
This method works well for light pollution since in Photo 1 the focus is usually set to infinity and in Photo 2 it will be set to just to a few cm, diffusing every star but the brightest into the background. Subtracting the background (Which is usually yellow/brown/green) will give a black background with the original stars. If you forgot to take photo 2 you can use the Blur function in a software but I think that taking a second photo is a better approach.<br />
This method turns the following photo - Iridium Flare in Corona Borealis (Northern Crown)<br />

<div dir="ltr" style="text-align: left;">

<div dir="ltr" style="text-align: left;">
But you can use this method even if you include terrestrial objects and even in daylight. Strong lights will diffuse but will still be noticeable and the entire image will look surrealistic.</div>
<div dir="ltr" style="text-align: left;">
Here is an example. What we see here is an Iridium flare near the constellation Cygnus (Swan), and the entire summer triangle including Vega at the top and Altair at the bottom-right. The photo was taken with a wide lens (16mm). The method will work better for longer focal lengths as the change of the focus will diffuse the strong lights better.</div>

I applied some more fixes to the photo such as:</div>
<div dir="ltr" style="text-align: left;">
</div>
<ol dir="ltr" style="text-align: left;">
<li>Remove the diffused bright stars (Vega and Deneb) - Single click of the Spot Heal tool around each star.</li>
<li>Remove the strayed light in the bottom-right caused by forgetting to cover the eyepiece during the long exposure - again one of the Heal tools did the trick.</li>
<li>Many crops (just the flare, just the summer circle, just the flare and the buildings, etc.) but here I show the full image.</li>
</ol>
<div class="separator" dir="ltr" style="clear: both; text-align: center;">
</div>
<div dir="ltr" style="text-align: left;">
The sky is much darker and probably some faint stars are not shown (more fine tuning in software is possible if you desire), but what is more incredible is what happened to the buildings.<br />

<b><span style="font-size: large;">Detailed Tutorial</span></b><br />
<br />
If you need an online free tool for this purpose you can use Pixlr. Here are the exact steps. The steps are identical for other software such as Photoshop or Lightroom but not everyone has them. Pixlr is a strong free alternative and has many features. However it might reduce the resolution of the image (There is a stronger desktop version but it is not free to use).<br />
<br />
1. Browse to <a href="https://pixlr.com/editor/" target="_blank">pixlr site</a>, choose "Open image from computer" and select your first photo (the photo with the correct focus).<br />
<table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody>

Mercury Transit is a rare occasion on which Mercury pass in front of the sun, a tiny tiny "eclipse".<br />
My setup was like this. I used a Bresser 130N and Canon DSLR to photograph through it, however there was a slight focus problem and there are no good results from it. Another Camera, Nikon P900 was mounted as piggyback on the scope and worked properly and Another Camera Canon SX50 for handheld photos and for the Sunset video below.<br />

The beginning was not very promising the entire sky were cloudy and the sun could hardly be seen. However from time to time there was some less clouds and it was possible to see the transit.</div>

<div dir="ltr" style="text-align: left;">
Mercury is an elusive planet. It is small, dim and most of the time to close to the sun to be seen at all. Yet , during its greatest elongation it is far enough from the Sun. In this period Mercury can is easy to spot after sunset or before sunrise.. Today 18-Apr-2016 Mercury is in greatest western elongation meaning it is easy to watch.</div>
<div dir="ltr" style="text-align: left;">
It is even easier as you can use the famous constellation Orion to help you find Mercury. Just continue the straight line from Orion's belt and go almost to the horizon and you will see Mercury. Actually Mercury is brighter than any of Orion's belt stars so you might be able to see it even before. Start watching about 45 minutes after sunset and look about 15 degrees up from the place the sun set. There is no other bright star in this area so when you finally see the white dot, it is mercury. And if you own a telescope try to observe Mercury and see its tiny but noticeable phase.</div>

<div dir="ltr" style="text-align: left;">
Astronomers don't like haze. It is bad. But even haze has it benefits and sometimes you can clearly see the sun through the haze without the need of filters which are otherwise a must. During sunset and the right amount of haze you might even be able to see sunspots with the naked eye as was the case today with sunspot AR2529. Also the swallows in the sky flew beyond it to create interesting photos And a nice video to start with<br />

But let's o back to the beginning. Here is a general photo of the sun. The haze makes the skies brown and yellow, quite eek, and the sun itself much dimmer than it should be.</div>

It is no secret that I like to photograph the ISS. Usually I concentrate in a single constellation and try to capture most of it with the bright line of the ISS. Such photos requires long exposure of 20-30 seconds. This is a recent example, Can you name the constellation?</div>

Such photos are not rare. Taking them from dark places (not like the one above) will show much more details including some DSOs. Even in the above photo there are some nice open clusters. Also to compensate for earth rotation a simple tracker can be used. Here you can read more about <a href="http://www.thevenustransit.com/2014/05/how-to-photograph-stars-and.html" target="_blank">how to photograph stars and constellations</a></div>

<div dir="ltr" style="text-align: left;">
I also tried to capture the ISS itself with my Nikon P900 which its main feature is the almost ridiculous zoom size which is equivalent to 2000mm. Setting the camera to high ISO, fast shutter and considering that the ISS is directly lit gives reasonable exposure. I will wait for a better pass when the ISS is almost directly above the head, and much closer to the observer. The general shape of the ISS is noticeable and this is an example that sometimes a thumbnails looks better.</div>

This photo is a single exposure. Jupiter is big enouch and bright enough to seen as a small disc with a yellow/orange color (You might need to enlarge the photo). As you can see I manage to capture both of them at the maximum zoom possible.</div>

<div dir="ltr" style="text-align: left;">
During the last year (and the one to come) there is an occultation of Aldebaran almost every month. However none of these occultations were visible from Israel. Not until today. Even when we finally can see the occultation, it was during the day, making it impossible to see with the naked eye.</div>
<div dir="ltr" style="text-align: left;">
Though let's not panic, Aldebaran is bright enough and can easily be seen with a telescope. The sky was not very clear but as I saw that it was only partially cloudy, I left work early and headed home to setup the telescope.</div>
<div dir="ltr" style="text-align: left;">
The first problem was to setup the mount correctly without seeing Polaris. Of course I should have set it up the night before but I was worried it might rain during the night and I didn't want to leave it outside even with a cover. So I "guesstimated" where the north is and hoped for the best, knowing that I would be making manual corrections during the observation.</div>
<div dir="ltr" style="text-align: left;">
Positioning the scope was easy. Next, I had to decide how to photograph the reappearance of Alderbaran. I chose a new method, which I had never tried previously, as I was using my brand new Nikon Coolpix P900 with an enormous zoom piggybacked on the scope.</div>
<div dir="ltr" style="text-align: left;">
Everything was ready and I just had to wait. I started a video recording and watched through the eyepiece. It was quite windy so the camera shook a little but in the video, you will be able to see the moon and suddenly a bright white dot! Yep - Aldebaran! Seeing it clearly through the eyepiece (in small magnification) was a very spectacular sight indeed.</div>
<div dir="ltr" style="text-align: left;">
So who said is it impossible to see stars during the day? BTW, Aldebaran's distance from Earth is 65 light years (the moon is only 1 light second) and its radius is 44 of that of the Sun. A real giant!</div>
<div dir="ltr" style="text-align: left;">
First of all here is a photo of my setup:</div>

<div dir="ltr" style="text-align: left;">
Exact setup is: Bresser N130 on EQ6-Pro (For visual) + Nikon P900 piggyback for the photos and videos.</div>
<div dir="ltr" style="text-align: left;">
<br /></div>
<div dir="ltr" style="text-align: left;">
Here is the video and some photos. In the video Aldebaran appears after about 6 seconds position equivalent to 2 o'clock. (make sure that you watch the video in HD on full screen).</div>

You will probably need to enlarge the photo as well. Notice Aldebaran on the bottom right (4 o'clock).</div>
