I have seen a full luinar eclipse in houston about 9 years ago. it was amazingly beautiful. the moon turned bright cranberry red as the earth's shadow overtook it. look for it tomorrow people!
The moon begins moving into Earth's shadow at 7:43 pm. Totality begins 78 minutes later at 9:01 pm and lasts for 51 minutes.
A total eclipse of the Moon occurs during the night of Wednesday, February 20/21, 2008. The entire event is visible from South America and most of North America (on Feb. 20) as well as Western Europe, Africa, and western Asia (on Feb. 21). During a total lunar eclipse, the Moon's disk can take on a dramatically colorful appearance from bright orange to blood red to dark brown an (rarely) very dark gray
An eclipse of the Moon can only take place at Full Moon, and only if the Moon passes through some portion of Earth's shadow. Th shadow is actually composed of two cone-shaped parts, one nested inside the other. The outer shadow or penumbra is a zone where Earth blocks some (but not all) of the Sun's rays. In contrast, the inner shadow or umbra is a region where Earth blocks all direct sunlight from reaching the Moon.
If only part of the Moon passes through the umbra, a partial eclipse is seen. However, if the entire Moon passes through the umbra shadow, then a total eclipse of the Moon occurs.
