A total lunar eclipse will occur at the Moon's ascending node of orbit on Sunday, November 18, 2040, with an umbral magnitude of 1.3991. It will be a central lunar eclipse, in which part of the Moon will pass through the center of the Earth's shadow. 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 5.7 days before apogee (on November 24, 2040, at 14:10 UTC), the Moon's apparent diameter will be smaller.
This is the second central lunar eclipse of Saros series 136, the first taking place on November 8, 2022.
Visibility The eclipse will be completely visible over east Africa, Europe, and Asia, seen rising over west Africa and eastern North and South America and setting over Australia and the western Pacific Ocean.

Eclipse season
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.
