A partial lunar eclipse occurred at the Moon’s ascending node of orbit on Wednesday, September 14, 1932,[1] with an umbral magnitude of 0.9752. 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 4.8 days before apogee (on September 19, 1932, at 17:00 UTC), the Moon's apparent diameter was smaller.[2]

This was the last of the first set of partial lunar eclipses in Lunar Saros 136, preceding the first total eclipse on September 26, 1950.
Visibility
editThe eclipse was completely visible over much of Africa, Europe, and west, central, and south Asia, seen rising over west Africa, South America, and eastern North America and setting over east and northeast Asia and Australia.[3]

Eclipse season
editThis 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.
