February 1952 lunar eclipse
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.
Visibility
The eclipse was completely visible over northeastern North America, eastern South America, Europe, Africa, and the Middle East, seen rising over much of North America and western South America and setting over much of Asia.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.| February 11 Descending node | February 25 Ascending node |
| Partial lunar eclipse Lunar Saros 113 | Total solar eclipse Solar Saros 139 |
