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).
