September 1941 lunar eclipse
A partial lunar eclipse occurred at the Moon’s descending node of orbit on Friday, September 5, 1941, with an umbral magnitude of 0.0511. 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 5.9 days before apogee, the Moon's apparent diameter was smaller.
Visibility
The eclipse was completely visible over much of Asia, Australia, and Antarctica, seen rising over Africa and Europe and setting over northeast Asia and the central Pacific Ocean.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.| September 5 Descending node | September 21 Ascending node |
| Partial lunar eclipse Lunar Saros 117 | Total solar eclipse Solar Saros 143 |
