A penumbral lunar eclipse occurred at the Moon’s ascending node of orbit on Monday, November 30, 2020,[1] with an umbral magnitude of −0.2602. 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 3.6 days after apogee (on November 26, 2020, at 19:30 UTC), the Moon's apparent diameter was smaller.[2]
This eclipse was the last of four penumbral lunar eclipses in 2020, with the others occurring on January 10, June 5, and July 5.
The eclipse was completely visible over northeast Asia and North America, seen rising over east Asia and Australia and setting over South America.[3]

See also: Eclipse cycle. This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight.
It is part of Saros cycle 116.
A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[5] This lunar eclipse is related to two partial solar eclipses of Solar Saros 123.
