September 2025 lunar eclipse

A total lunar eclipse occurred at the Moon's ascending node of orbit on Sunday, September 7, 2025, with an umbral magnitude of 1.3638. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A total lunar eclipse occurs when the Moon's near side entirely passes into the Earth's umbral shadow. Unlike a solar eclipse, which can only be viewed from a relatively small area of the world, a lunar eclipse may be viewed from anywhere on the night side of Earth. A total lunar eclipse can last up to nearly two hours, while a total solar eclipse lasts only a few minutes at any given place, because the Moon's shadow is smaller. Occurring about 2.6 days before perigee (on Wednesday, September 10, 2025, at 8:10 UTC), the Moon's apparent diameter was larger. This lunar eclipse was the second of an almost tetrad, with the others being on March 14, 2025 (total); March 3, 2026 (total); and August 28, 2026 (partial).
