The Full July Buck Moon happens this weekend plus a partial penumbral lunar eclipse!

Science

Just after midnight Sunday is the July Full Moon (NASA SKYCAL). This Full Moon is sometimes called the Buck Moon. Additionally, the Moon will be at aphelion or the farthest point from Earth in its orbit.

A penumbral lunar eclipse will also occur just after midnight early Sunday. This eclipse will be visible in North America. A penumbral eclipse occurs when the Moon passes through the outer shadow of the Earth, which is called the penumbra.

Penumbral eclipses can be harder to discern than partial or total eclipses and at best you may notice that the surface of the Moon appears to be shaded darker during the eclipse. The maximum eclipse occurs at 12:30 AM EDT Sunday.

The image below shows where this penumbral lunar eclipse will be visible.
