A partial lunar eclipse occurred at the Moon's ascending node of orbit on Saturday, February 20, 1943, with an umbral magnitude of 0.7616. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A partial lunar eclipse occurs when one part of the Moon is in the Earth's umbra, while the other part is in the Earth's penumbra. 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. Occurring about 3.8 days after apogee (on February 16, 1943, at 9:00 UTC), the Moon's apparent diameter was smaller.
Visibility The eclipse was completely visible over North and South America, seen rising over northeast Asia and the central Pacific Ocean and setting over Africa, Europe, and the Middle East.

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.
