Dec 21, 2010 Total Lunar Eclipse

The total lunar eclipse on December 21, 2010, is the last eclipse of the year. This is second of two lunar eclipses in 2010. The last time a total lunar eclipse occurred before that was on February 21, 2008.

What this lunar eclipse looks like

The animation shows approximately what the eclipse looks like from the night side of earth.

This is an approximate representation. The eclipse and moon will look slightly different in real life.

This is a total lunar eclipse.

Is this eclipse viewable in London?

The animation shows where this total lunar eclipse is visible during the night (dark “wave” slowly moving across the Earth's surface).

The night (dark) areas in the animation are approximately those that can see the moon, and therefore also the eclipse.


Intense red shading: Observers within this area can see the eclipse from beginning to end.

Red shading right/east of intense shading: Observers within this area can see the eclipse after moonrise/sunset.

Red shading left/west of intense shading: Observers within this area can see the eclipse until moonset/sunrise.

No coloring: Eclipse is not visible at all

Note: Actual eclipse visibility depends on weather conditions
