December 1945 lunar eclipse
A total lunar eclipse occurred at the Moon’s ascending node of orbit on Wednesday, December 19, 1945, with an umbral magnitude of 1.3424. 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 1.6 days after perigee, the Moon's apparent diameter was larger.
Visibility
The eclipse was completely visible over much of North and South America, west Africa, Europe, and northern Russia, seen rising over the eastern Pacific Ocean and setting over east and southern Africa and much of Asia.Eclipse details

Eclipse season
This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months 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.| December 19 Ascending node | January 3 Descending node |
| Total lunar eclipse Lunar Saros 124 | Partial solar eclipse Solar Saros 150 |
