A total lunar eclipse took place on December 10, 2011. It was the second of two total lunar eclipses in 2011, the first having occurred on June 15. A lunar eclipse occurs when the moon is positioned just right in its orbit to pass through Earth's shadow.


NASA chart of the eclipse

Asia, Australia, and other areas of the Pacific had the best visibility. European countries only saw a partial eclipse of a rising moon, while northwestern North America saw a partial eclipse of a setting moon.

The eclipse was seen over the Philippines despite cloudy and rainy weather over parts of Luzon and other areas. Photos were taken by groups of amateur astronomers from the Astronomical League of the Philippines (ALP).

South America and portions of West Africa missed the eclipse completely as it happened in the early morning.

Lunar year (354 days)[edit]

This eclipse is the one of four lunar eclipses in a short-lived series. The lunar year series repeats after 12 lunations or 354 days (shifting back about 10 days in sequential years). Because of the date shift, the Earth's shadow will be about 11 degrees west in sequential events.
