A partial lunar eclipse will occur at the Moon’s ascending node of orbit on Friday, August 28, 2026, with an umbral magnitude of 0.9319. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A partial lunar eclipse occurs when one part of the Moon is in the Earth's umbra, while the other part is in the Earth's penumbra. 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. Occurring about 6 days after perigee (on August 22, 2026, at 4:20 UTC), the Moon's apparent diameter will be larger.
This lunar eclipse will be the last of an almost tetrad, with the others being on March 14, 2025 (total); September 8, 2025 (total); and March 3, 2026 (total).
