Today’s eclipse will be what astronomers dub a “penumbral eclipse,” which occurs when the outer ring of Earth’s shadow just grazes the moon. (During a partial eclipse, the moon falls somewhat into Earth’s inner shadow; during a total lunar eclipse it falls entirely into that inner shadow.)

But it will take a keen eye indeed to notice the penumbral darkening, which will just tint the lower edge of the moon at the midpoint of the eclipse. 

The eclipse will also be geographically limited, visible only over central and east Africa, Eastern Europe, western and central Asia, and parts of Indonesia and Australia. It will begin at 1:45 p.m. EDT (1745 GMT) and end at 5:04 p.m. EDT (2104 GMT), according to a NASA chart. 

Weather permitting, skywatchers who won’t be able to check out the eclipse for themselves can still keep tabs on the moon digitally, thanks to a livestream from the Virtual Telescope Project. The show will begin today at 3 p.m. EDT (1900 GMT), offering lunar views from Rome, depending on the weather there. 

And if you miss today’s display, the summer promises another penumbral lunar eclipse on July 5, although that eclipse will be even fainter than this one. That one will be visible from North and South America, as well parts of Europe and most of Africa. The June and July lunar eclipses are the second and third in a series of four penumbral lunar eclipses in 2020 that began on January 10. The fourth one will occur on Nov. 30.

June will also bring skywatchers a second eclipse, this time an eclipse of the sun. On June 21, the moon will pass in front of the sun as seen from Earth but won’t completely cover the star, leaving a so-called “ring of fire” around its outer edge. The annular eclipse, as its known, will be the first solar eclipse of 2020.
