A total lunar eclipse occurred at the Moon’s descending node of orbit on Wednesday, January 8, 1936,[1] with an umbral magnitude of 1.0173. 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 6.2 days before apogee (on January 14, 1936, at 23:50 UTC), the Moon's apparent diameter was smaller.[2]
Visibility
[edit]The eclipse was completely visible over eastern Europe, Asia, and western Australia, seen rising over Africa andwestern Europe and setting over eastern Australia, northwestern North America, and the central Pacific Ocean.[3]

Eclipse season
[edit]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.
