A total lunar eclipse occurred at the Moon’s descending node of orbit on Monday, November 7, 1938, with an umbral magnitude of 1.3525. 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 3.2 days before perigee (on November 11, 1938, at 3:25 UTC), the Moon's apparent diameter was larger.

This lunar eclipse was the second of an almost tetrad, with the others being on May 14, 1938 (total); May 3, 1939 (total); and October 28, 1939 (partial).

Visibility The eclipse was completely visible over Africa, Europe, and west and central Asia, seen rising over North and South America and setting over east Asia and western Australia.

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.
