🌍 About This Eclipse

A partial lunar eclipse occurs when the Earth passes between the Sun and the Moon, but they are not perfectly aligned. This causes only a portion of the Moon to be covered by the Earth's shadow, resulting in a partial darkening of the Moon's surface.

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.
