A partial lunar eclipse occurred at the Moon’s ascending node of orbit on Saturday, July 4, 1936, with an umbral magnitude of 0.2668. 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. The Moon's apparent diameter was near the average diameter because it occurred 6.8 days after apogee (on June 27, 1936, at 21:30 UTC) and 7.2 days before perigee (on July 11, 1936, at 22:05 UTC).
Visibility The eclipse was completely visible over south and east Asia, Australia, and Antarctica, seen rising over Africa, Europe, and west and central Asia and setting over northeast Asia and the central Pacific Ocean.

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.
