As fireworks finish up this 4th of July, look skyward to see the first of two penumbral lunar eclipses for 2020. A penumbral lunar eclipse occurs when the moon passes through the outer shadow of Earth.
As viewed from the Moon, the Earth only partially covers the Sun. Thus with the lunar surface still receiving sunlight, albeit limited, the challenge is seeing the subtle shadow on the Moon. The best time to look is at the peak which occurs at 11:30pm. As shown in the simulation below, the roughly top 25% will be shadowed.
The eclipse begins at 10:07pm (probably be closer to 11pm before you'll notice any shadowing). The peak is 11:30pm The Full 'Buck' Moon occurs at 11:44pm Eclipse ends at 12:52am.
The next penumbral eclipse will occur during the early morning hours of Nov. 30th
