July 2020's full Moon brings with it a penumbral eclipse, which occurs when the Moon crosses through the faint outer edge of Earth’s shadow (the penumbra), making part of the Moon appear ever-so-slightly darker than usual. Unlike a full lunar or solar eclipse, the visual effect of a penumbral eclipse is usually so minimal that it can be difficult to perceive at all. For this eclipse, only a small portion of the Moon will cross into the penumbra, making it even more difficult to see.
This eclipse will be visible from most of North America, except in the northernmost regions of Canada and Alaska. It will begin at 11:04 P.M. EDT on July 4 and end at 1:56 A.M. EDT on July 5, 2020.
