January 2038 lunar eclipse
A penumbral lunar eclipse will occur at the Moon’s ascending node of orbit on Thursday, January 21, 2038, with an umbral magnitude of −0.1127. 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 3.1 days before perigee, the Moon's apparent diameter will be larger.
This eclipse will be the first of four penumbral lunar eclipses in 2038, with the others occurring on June 17, July 16, and December 11.
Visibility
The eclipse will be completely visible over North and South America, west Africa, and Europe, seen rising over the eastern Pacific Ocean and setting over east Africa and west and central Asia.Eclipse details

Eclipse season
This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months 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.| January 5, 2038|January 5] Descending node | January 21 Ascending node |
