Total Lunar Eclipse: December 21 2010



The total lunar eclipse of December 21 2010 will be visible over eastern Asia, Australasia, northwestern Europe and Africa, and the Americas. The Moon will be well within the Earth's umbral shadow, in a total eclipse that will last over an hour.

The penumbral eclipse -- the least exciting, and hardest to see part -- will begin at 05:27:43 UT and end at 11:06:04 UT. It will be visible from northwestern Europe, Africa and south America when it begins around Moonset; north America and the Pacific; and eastern Asia and Australasia when it ends at around Moonrise.

The partial eclipse will begin at 06:32:17 UT and end 3½ hours later at 10:01:39 UT, and will be visible from a slightly smaller area. The total eclipse lasts for over one hour; it begins at 07:40:21 UT and ends at 08:53:34 UT, with the moment of greatest eclipse at 08:16:56 UT. It is visible over Britain and northwest Europe at Moonset (dawn); the Pacific and the Americas; and northeast Asia around Moonrise (Sunset).

The total eclipse should be a spectacular sight; the Moon will be well within the Earth's umbral shadow, the umbral magnitude being 1.261, and should be stained dark red by the Earth's atmosphere. Don't miss it!
