A penumbral lunar eclipse occurred at the Moon’s ascending node of orbit on Saturday, August 5, 1933, with an umbral magnitude of −0.7336. 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 2.1 days after perigee (on August 3, 1933, at 17:40 UTC), the Moon's apparent diameter was larger.
This eclipse was the third of four penumbral lunar eclipses in 1933, with the others occurring on February 10, March 12, and September 4.
