January 1954 lunar eclipse
A total lunar eclipse occurred at the Moon’s descending node of orbit on Tuesday, January 19, 1954, with an umbral magnitude of 1.0322. 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 6.4 days before apogee, the Moon's apparent diameter was smaller.
Visibility
The eclipse was completely visible over much of North and South America, west Africa, and Europe, seen rising over western North America and the eastern Pacific Ocean and setting over southern and east 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.| January 5 Ascending node | January 19 Descending node |
| Annular solar eclipse Solar Saros 121 | Total lunar eclipse Lunar Saros 133 |
