Good morning, Rallypoint. Today's Astronomy Picture of the Day (APOD) is titled "Lunar Eclipse Perspectives." There's a lot going on in today's composite image. When you mouse over the APOD, the different labels disappear (at least that's how it worked for me). That allows one to clearly see the difference between how the Moon looked to a viewer in the American versus the European Hemispheres. But what is most interesting is the label "LI-21J". A meteorite estimated to be 10-27 centimeters (4-10 inches) in diameter and weighing between 7-40 kilograms (15-88 pounds) impacted the Moon during the eclipse. Scientists estimated the velocity at impact at 47,000 kilometers per hour (8 miles per second). If the size and velocity assumptions are correct, there will be an impact crater at least 5 meters (16 feet) for a future lunar probe to investigate. Pretty cool stuff.

Thank you, my friend Maj William W. 'Bill' Price for posting the NASA Astronomy Picture of the Day (APOD) for Wednesday, February 5, 2020 entitled "Lunar Eclipse Perspectives."

"Explanation: Do we all see the same Moon? Yes, but we all see it differently. One difference is the apparent location of the Moon against background stars -- an effect known as parallax. We humans use the parallax between our eyes to judge depth. To see lunar parallax, though, we need eyes placed at a much greater separations -- hundreds to thousands of kilometers apart. Another difference is that observers around the Earth all see a slightly different face of our spherical Moon -- an effect known as libration. The featured image is a composite of many views across the Earth, as submitted to APOD, of the total lunar eclipse of 2019 January 21. These images are projected against the same background stars to illustrate both effects. The accurate superposition of these images was made possible by a serendipitous meteorite impact on the Moon during the lunar eclipse, labeled here L1-21J -- guaranteeing that these submitted images were all taken within a split second."
