Apr 22, 1940 Penumbral Lunar Eclipse

What this lunar eclipse looks like

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

This is a penumbral lunar eclipse.

The animation shows where this penumbral 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.

Legend

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 until moonset/sunrise.

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

No coloring: Eclipse is not visible at all

Note: Actual eclipse visibility depends on weather conditions and line of sight to the Moon.

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