A partial lunar eclipse will occur at the Moon’s descending node of orbit on Monday, January 22, 2046,{{cite web|title=January 22–23, 2046 Partial Lunar Eclipse|url=https://www.timeanddate.com/eclipse/lunar/2046-january-22|publisher=timeanddate|access-date=6 December 2024}} with an umbral magnitude of 0.0550. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A partial lunar eclipse occurs when one part of the Moon is in the Earth's umbra, while the other part is in 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 1.1 days before perigee (on January 23, 2046, at 14:00 UTC), the Moon's apparent diameter will be larger.{{cite web|title=Moon Distances for London, United Kingdom, England|url=https://www.timeanddate.com/astronomy/moon/distance.html?year=2046&n=136|publisher=timeanddate|access-date=6 December 2024}}

Visibility

The eclipse will be completely visible over Australia, east and north Asia, and northwestern North America, seen rising over eastern Europe and west, central, and south Asia and setting over much of North America.{{cite web|title=Partial Lunar Eclipse of 2046 Jan 22|url=https://eclipse.gsfc.nasa.gov/LEplot/LEplot2001/LE2046Jan22P.pdf|publisher=NASA|access-date=6 December 2024}}

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.
