A penumbral lunar eclipse occurred at the Moon’s descending node of orbit on Sunday, March 12, 1933, with an umbral magnitude of −0.4153. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A penumbral lunar eclipse occurs when part or all of the Moon's near side passes into 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 3.5 days before perigee (on March 15, 1933, at 17:25 UTC), the Moon's apparent diameter was larger.
This eclipse was the second of four penumbral lunar eclipses in 1933, with the others occurring on February 10, August 5, and September 4.
