A total lunar eclipse occurred at the Moon’s ascending node of orbit on Tuesday, September 26, 1950, with an umbral magnitude of 1.0783. 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 5.1 days before apogee (on October 1, 1950, at 5:30 UTC), the Moon's apparent diameter was smaller.

This lunar eclipse was the last of a tetrad, with four total lunar eclipses in series, the others being on April 13, 1949; October 7, 1949; and April 2, 1950.

Visibility The eclipse was completely visible over much of North and South America, seen rising over northwestern North America and the central Pacific Ocean and setting over Africa, Europe, and the Middle East.

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. 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.
