A total lunar eclipse will occur at the Moon’s descending node of orbit on Wednesday, March 25, 2043,[1] with an umbral magnitude of 1.1161. 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 3.4 days before apogee (on March 29, 2043, at 1:30 UTC), the Moon's apparent diameter will be smaller.[2]
This lunar eclipse is the first of a tetrad, with four total lunar eclipses in series, the others being on September 19, 2043; March 13, 2044; and September 7, 2044.
The eclipse will be completely visible over east Asia, Australia, and the western Pacific Ocean, seen rising over central and east Africa, eastern Europe, and west, central, and south Asia and setting over much of North America.[3]

See also: Eclipse cycle. This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) 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.
A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[5] This lunar eclipse is related to two total solar eclipses of Solar Saros 130.
