A penumbral lunar eclipse occurred at the Moon’s descending node of orbit on Friday, February 10, 1933, with an umbral magnitude of −1.0268. 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. The Moon's apparent diameter was near the average diameter because it occurred 6.7 days after apogee (on February 3, 1933, at 21:10 UTC) and 7.9 days before perigee (on February 18, 1933, at 10:50 UTC).
This eclipse was the first of four penumbral lunar eclipses in 1933, with the others occurring on March 12, August 5, and September 4.
