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).
Visibility The eclipse was completely visible over east Africa, Asia, and central and west Australia. It was seen when rising over most of Africa and Europe, and when setting over the central Pacific Ocean.

Eclipse season
This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight.
