A penumbral lunar eclipse occurred at the Moon’s ascending node of orbit on Sunday, June 5, 1955, with an umbral magnitude of −0.4498. 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 only about 11 hours after apogee (on June 5, 1955, at 3:45 UTC), the Moon's apparent diameter was smaller.
