Description of video of the total lunar eclipse. The Moon begins in its familiar shade of white. It turns a lighter shade of gray as it enters Earth’s outer fainter Penumbra shadow. As the Moon moves further into Earth’s shadow it enters Earth’s deep umbra (the dark shadow of Earth cast into Space) and the edge of the Moon begins to disappear. Then as it gradually moves deeper into Earth’s umbra, the Moon begins to redden on its western hemisphere, followed by a uniform copper red across the surface of the Moon. The Moon reddens even more the deeper it becomes immersed in the shadow of Earth. The Moon is illuminated indirectly.
Sunlight strikes Earth’s atmosphere, where fine particles of dust, volcanic ash, and water vapour, refract and bend light inwards towards the Moon. The reddish light strikes the Lunar surface which in turn is reflected back to Earth. Now even deeper in Earth’s umbra shadow, the Moon becomes a darker red as less light is able to reach the lunar surface.
Orbital velocity of the Moon; 2,288 miles per hour/3,683kph. And although the duration of this eclipse, 15 June 2011, was extremely long, it seemed to have passed so very quickly, and the eclipse fades away again, the Moon gradually begins to lose its beautiful subtle crimson copper red, turning back to the normal and familiar shade of white.
