April 2051 lunar eclipse
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, 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.Eclipse details

Eclipse season
This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months 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.| April 11, 2051|April 11] Descending node | April 26 Ascending node |
