Saturday, Dec 10th 2011, large parts of the world were able to
see a lunar eclipse. This shall not repeat until atleast 2014 now.
"The entire lunar eclipse was visible in East Asia, Australia, and the far western portion of North America that included Alaska and Canada's Yukon and Northwest Territories. The spectacle lasted nearly three and a half hours, starting on Saturday at 4:45 a.m. Pacific Time."[1]

Lunar Eclipse Geometry
A lunar eclipse occurs when the Moon passes behind the Earth so that the Earth blocks the Sun's rays from striking the Moon. This can occur only when the Sun, Earth, and Moon are aligned exactly, or very closely so, with the Earth in the middle. Hence, a lunar eclipse can only occur the night of a full moon[2]
