Minor Lunar Eclipse expected this Friday night

Lunar eclipse chart
The moon will pass through Earth's faint outer shadow, known as the penumbra, this Friday evening, with the time of the deepest eclipse occurring at 7:50pm ET.  People in the Mountain and Pacific time zones may not see the eclipse since this will occur in the later afternoon hours before the moon rises.

Lunar eclipses occur when Earth's core (umbral) shadow falls across the moon, casting it in shadow.  During a partial eclipse, the umbra covers only a part of the moon, while a penumbral eclipse involves only Earth's fainter outer shadow, causing a much less dramatic dimming effect.  The effect of a penumbra eclipse is subtle compared to a total lunar eclipse, but it's still worth the watch!
