Minor Lunar Eclipse expected this Friday night
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!
