The Moon During a Total Lunar Eclipse

How does the Moon’s appearance change during a total lunar eclipse? The featured time-lapse video was digitally processed to keep the Moon bright and centered during the 5-hour eclipse of 2018 January 31. At first the full moon is visible because only a full moon can undergo a lunar eclipse. Stars move by in the background because the Moon orbits the Earth during the eclipse. The circular shadow of the Earth is then seen moving across the Moon. The light blue hue of the shadow’s edge is related to why Earth’s sky is blue, while the deep red hue of the shadow’s center is related to why the Sun appears red when near the horizon. Tomorrow, people living from southeast Asia, across the Pacific, to the southwest Americas may get to see a Blood Supermoon Total Lunar Eclipse. Here the term blood refers to the (likely) red color of the fully eclipsed Moon, while the term supermoon indicates the Moon’s slightly high angular size — due to being relatively close to the Earth in its slightly elliptical orbit. via NASA

Wikipedia article of the day is Operation Rösselsprung (1944). Check it out: Article-Link Summary: Operation Rösselsprung was a combined airborne and ground assault by the German XV Mountain Corps on the Supreme Headquarters of the Yugoslav Partisans during World War II. Launched on 25 May 1944, the operation was aimed at the Partisan leader Marshal Josip Broz Tito (pictured) and his headquarters. It is associated with the Seventh Enemy Offensive. The operation involved direct action via an airborne assault by the 500th SS Parachute Battalion and a planned subsequent link-up with ground forces, including Home Guard forces of the Independent State of Croatia and collaborationist Chetniks. Tito, his principal staff and Allied military personnel escaped. The operation failed due to fierce Partisan resistance, the failure of the various German intelligence agencies to share the limited intelligence available on Tito’s exact location, and the lack of contingency planning by the commander of the German airborne force.
