A partial lunar eclipse occurred at the Moon’s descending node of orbit on Monday, February 11, 1952, with an umbral magnitude of 0.0832. 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 2.7 days after apogee, the Moon's apparent diameter was smaller.
