July 4–5, 2020 Penumbral Lunar Eclipse

The Earth's faint outer shadow or penumbra will partially cover the face of the Full Moon during this Buck Moon eclipse. Because of its subtlety, observers in North America, South America, and Africa may find it hard to see part of the Moon darken during the maximum phase of this penumbral lunar eclipse.

What This Lunar Eclipse Looked Like

The curvature of the shadow's path and the apparent rotation of the Moon's disk is due to the Earth's rotation.

Eclipse Map and Animation

The animation shows where this penumbral 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.

Note that since it is a penumbral eclipse, it can be hard to see, as the Moon will only be a bit fainter.

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.
