A total lunar eclipse will occur at the Moon’s ascending node of orbit on Wednesday, April 26, 2051, with an umbral magnitude of 1.2034. 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 after apogee (on April 23, 2051, at 12:00 UTC), the Moon's apparent diameter will be smaller.

This lunar eclipse is the third of a tetrad, with four total lunar eclipses in series, the others being on May 6, 2050; October 30, 2050; and October 19, 2051.

Visibility

The eclipse will be completely visible over South America and west Africa, seen rising over North America and the eastern Pacific Ocean and setting over central and east Africa, Europe, and west, central, and south Asia.
