A penumbral lunar eclipse will occur at the Moon’s descending node of orbit on Sunday, August 27, 2045, with an umbral magnitude of −0.3899. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A penumbral lunar eclipse occurs when part or all of the Moon's near side passes into 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 1.6 days after apogee (on August 26, 2045, at 0:10 UTC), the Moon's apparent diameter will be smaller.

Visibility

The eclipse will be completely visible over east Asia and Australia, seen rising over east Africa and west, central, and south Asia and setting over western North America.
