A penumbral lunar eclipse occurred at the Moon’s ascending node of orbit on Saturday, May 25, 2013,[1] with an umbral magnitude of −0.9322. 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 18 hours before perigee (on May 25, 2013, at 21:40 UTC), the Moon's apparent diameter was larger.[2]
This eclipse was visually imperceptible due to the small entry into the penumbral shadow. It also marked the beginning of Saros series 150.
