A partial lunar eclipse occurred at the Moon’s ascending node of orbit on Tuesday, October 7, 1930, with an umbral magnitude of 0.0253. 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 4.4 days after apogee (on October 3, 1930, at 9:45 UTC), the Moon's apparent diameter was smaller.
