A penumbral lunar eclipse will occur at the Moon’s descending node of orbit on Sunday, December 20, 2048, with an umbral magnitude of −0.1420. 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 13 hours before apogee (on December 20, 2048, at 19:30 UTC), the Moon's apparent diameter will be smaller.

Visibility The eclipse will be completely visible over North America and much of South America, seen rising over northeast Asia and the western Pacific Ocean and setting over west and central Africa and Europe.

Eclipse season

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.
