August 1942 lunar eclipse
A total lunar eclipse occurred at the Moon’s descending node of orbit on Wednesday, August 26, 1942,[1] with an umbral magnitude of 1.5344. 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.[2] This was a central lunar eclipse, with the Moon passing through the darkest portion of the earth's umbral shadow. VisibilityThe 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.[3] Eclipse detailsShown below is a table displaying details about this particular solar eclipse. It describes various parameters pertaining to this eclipse.[4]
Eclipse seasonThis 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.

Saros 127Lunar saros series 127, repeating every 18 years and 11 days, has a total of 72 lunar eclipse events including 54 umbral lunar eclipses (38 partial lunar eclipses and 16 total lunar eclipses). Solar Saros 134 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.
Inex seriesThe inex series repeats eclipses 20 days short of 29 years, repeating on average every 10571.95 days. This period is equal to 358 lunations (synodic months) and 388.5 draconic months. Saros series increment by one on successive Inex events and repeat at alternate ascending and descending lunar nodes. This period is 383.6734 anomalistic months (the period of the Moon's elliptical orbital precession). Despite the average 0.05 time-of-day shift between subsequent events, the variation of the Moon in its elliptical orbit at each event causes the actual eclipse time to vary significantly. It is a part of Lunar Inex series 40. All events in this series shown (from 1000 to 2500) are central total lunar eclipses.
Half-Saros cycleA lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[5] This lunar eclipse is related to two total solar eclipses of Solar Saros 134.
