🌍 About This Eclipse

A penumbral lunar eclipse occurs when the Moon passes through the Earth's penumbral shadow. This type of eclipse is subtle and often hard to observe, as the Moon only slightly darkens. It is not as dramatic as a partial or total lunar eclipse, but it is still an interesting astronomical event.

A lunar eclipse is a geocentric event. The contacts and magnitudes on this page are the same for every observer who can see the Moon at that moment.
