Template:Short description Template:Infobox lunar eclipse A penumbral lunar eclipse will occur at the Moon’s descending node of orbit on Thursday, October 30, 2031,[1] with an umbral magnitude of −0.3193. 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. The Moon's apparent diameter will be near the average diameter because it will occur 7.6 days after perigee (on October 22, 2031, at 16:20 UTC) and 6.6 days before apogee (on November 5, 2031, at 21:45 UTC).[2]

Visibility

The eclipse will be completely visible over North America, western South America, and the eastern Pacific Ocean, seen rising over eastern Australia and northeast Asia and setting over eastern South America, west Africa, and western Europe.[3]

Eclipse season

Script error: No such module "Labelled list hatnote". 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.
