A total lunar eclipse occurred at the Moon’s descending node of orbit on Wednesday, August 26, 1942,{{cite web|title=August 25–26, 1942 Total Lunar Eclipse (Blood Moon)|url=https://www.timeanddate.com/eclipse/lunar/1942-august-26|publisher=timeanddate|access-date=19 December 2024}} with an umbral magnitude of 1.5344. It was a central lunar eclipse, in which part of the Moon passed 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 2.7 days after perigee (on August 23, 1942, at 9:50 UTC), the Moon's apparent diameter was larger.{{cite web|title=Moon Distances for London, United Kingdom, England|url=https://www.timeanddate.com/astronomy/moon/distance.html?year=1942&n=136|publisher=timeanddate|access-date=19 December 2024}}
Visibility
The eclipse was completely visible over eastern North America, South America, west Africa, and Antarctica, seen rising over western North America and the eastern Pacific Ocean and setting over Africa, Europe, and the Middle East.{{cite web|title=Total Lunar Eclipse of 1942 Aug 26|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot1901/LE1942Aug26T.pdf|publisher=NASA|access-date=19 December 2024}}

Eclipse season
{{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. The first and last eclipse in this sequence is separated by one synodic month.
