A total lunar eclipse will occur at the Moon's descending node of orbit on Saturday, October 8, 2033, with an umbral magnitude of 1.3508. 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 only about 3 hours after perigee (on October 8, 2033, at 8:15 UTC), the Moon's apparent diameter will be larger.
This lunar eclipse is the last of a tetrad, with four total lunar eclipses in series, the others being on April 25, 2032; October 18, 2032; and April 14, 2033.
This will also be a supermoon, the first supermoon lunar eclipse since May 16 in 2022.
Visibility The eclipse will be completely visible over northeast Asia, eastern Australia, western North America and the Pacific Ocean, seen rising over most of Asia and western Australia and setting over eastern North America and South America.

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.
