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.

Visibility

The eclipse was completely visible over east, Australia, and Antarctica, seen rising over the western half of Asia and east Africa and setting over the eastern Pacific Ocean.
