A penumbral lunar eclipse occurred at the Moon’s ascending node of orbit on Friday, January 10, 2020, with an umbral magnitude of −0.1146. 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 2.8 days before perigee (on January 13, 2020, at 15:20 UTC), the Moon's apparent diameter was larger.
This eclipse was the first of four penumbral lunar eclipses in 2020, with the others occurring on June 5, July 5, and November 30.
