A penumbral lunar eclipse occurred at the Moon’s ascending node of orbit on Saturday, February 11, 2017, with an umbral magnitude of −0.0342. 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 4.6 days before perigee (on February 6, 2017, at 9:00 UTC), the Moon's apparent diameter was larger.

This eclipse occurred the same day as comet 45P/Honda–Mrkos–Pajdušáková made a close approach to Earth (0.08318 AU). It also occurred on the Lantern Festival, the first eclipse to do so since February 9, 2009.

Visibility

The eclipse was completely visible over northeastern North America, eastern South America, Europe, Africa, and west Asia, seen rising over much of North America and western South America and setting over south and east Asia.
