The Moon's hourly motion across the Earth's shadow in the constellation of Gemini

A partial lunar eclipse was visible on 31 December 2009. It was the last and largest of four minor lunar eclipses in 2009. This lunar eclipse was also notable, because it occurred during a blue moon (a second full moon in December) and was near perigee (making it a supermoon). The next eclipse on New Year's Eve and blue moon will occur on 31 December 2028.

Only a small portion of the Moon entered the Earth's umbral shadow, but there was a distinct darkening visible over the Moon's southern surface at greatest eclipse.

Visibility

NASA chart of the eclipse

It was visible from all of Africa, Europe, Asia, Middle East and Australia. In the Philippines, the lunar eclipse was started last 1 January 2010, when it was very visible at mid-dawn until before sunrise.


This simulation shows the view of the Earth as viewed from the center of the Moon at greatest eclipse. The partially eclipsed Sun is visible above the north pole.
