Lunar eclipse on Dec 21st 2010

Hi,

Lunar eclipse occurs when the moon is blocked by the earth's shadow as the earth passes between the moon and the sun. Dec. 21st is also called the winter solstice, the longest night of the year(in the northern hemisphere).

The first video shows the shadow falling on the moon from the left hand side of the moon and progress over the moon as the satellite revolves around the earth. Then the red coloured moon is due to the diffused light(penumbra) falling on the moon from the sun. Then the moon lights up from the left side again with direct light from the sun as it emerges from the shadow of the earth.



The second video is an incredible time lapse video of the total lunar eclipse from KxbTV on YouTube, produced by Kareem Brown.



Cheers
