(UPI) -- The moon will hide behind Earth's shadow Friday evening in a lunar eclipse that will be visible to skywatchers around the world.
More specifically, the moon will pass through Earth's outer shadow, or penumbra. The eclipse will be at its deepest at 7:50 p.m. EDT.
Though the penumbral eclipse will be subtle compared to a total lunar eclipse, SPACE.com still encourages science lovers to crane their necks skyward for the show.
"Unusual shading on the southern half of the moon should be fairly plain," Sky and Telescope's Alan MacRobert wrote on Sunday. "Look for the penumbral shadow to move from (celestial) east to west across the disc. You might be able to detect lesser traces of penumbral shading for about 45 minutes before and after mid-eclipse."
