Eclipse Map and Animation

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

Shades of darkness

Night, moon high up in sky.

Moon between 12 and 18 degrees above horizon.

Moon between 6 and 12 degrees above horizon. Make sure you have free line of sight.

Moon between 0 and 6 degrees above horizon. May be hard to see due to brightness and line of sight.

Day, moon and eclipse both not visible.

Note: Twilight will affect the visibility of the eclipse, as well as weather.

Eclipse was visible.

Only partial phase was visible. Missed partial phase.

Eclipse was not visible at all.

Note: Areas with lighter shadings left (West) of the center will experience the eclipse after moonrise/sunset. Areas with lighter shadings right (East) of the center will experience the eclipse until moonset/sunrise. Actual eclipse visibility depends on weather conditions and line of sight to the Moon.

An Eclipse Never Comes Alone!

A solar eclipse always occurs about two weeks before or after a lunar eclipse.

Usually, there are two eclipses in a row, but other times, there are three during the same eclipse season.
