A total lunar eclipse will occur at the Moon’s descending node of orbit on Wednesday, January 1, 2048,^[1] with an umbral magnitude of 1.1297. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A total lunar eclipse occurs when the Moon's near side entirely passes into the Earth's umbral shadow. 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. A total lunar eclipse can last up to nearly two hours, while a total solar eclipse lasts only a few minutes at any given place, because the Moon's shadow is smaller. Occurring about 4.4 days after apogee (on December 27, 2047, at 21:50 UTC), the Moon's apparent diameter will be smaller.^[2]

This will be the first recorded lunar eclipse to be visible on New Year's Day for nearly all of Earth's timezones. The next such eclipse will occur in 2094.

Visibility

The eclipse will be completely visible over North America and western South America, seen rising over east and northeast Asia and eastern Australia and setting over much of Africa and Europe.^[3]

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.
