A penumbral lunar eclipse will occur at the Moon’s descending node of orbit on Monday, December 9, 2030,[1] with an umbral magnitude of −0.1613. 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 7.5 hours before apogee (on December 10, 2030, at 5:05 UTC), the Moon's apparent diameter will be smaller.[2]

Visibility

The eclipse will be completely visible over Africa, Europe, and north, west, central, and south Asia, seen rising over North and South America and setting over east Asia and western Australia.[3]

Eclipse season

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.
