A total lunar eclipse will take place on 7-8 September 2025. The Moon will barely miss the center of the Earth's shadow. It will be the second of two total lunar eclipses. Occurring roughly 3 days before perigee, the Moon will appear larger than usual.

This eclipse is the second of an almost tetrad, with others being 14 Mar 2025 (T), 03 Mar 2026 (T) and 28 Aug 2026 (P).

Visibility

It will be completely visible over much of Asia, Australia and eastern Africa, will be seen rising over the rest of Africa and Europe, and setting over eastern Asia and New Zealand.
