August 2072 lunar eclipse

A total lunar eclipse will occur at the Moon’s descending node of orbit on Sunday, August 28, 2072, with an umbral magnitude of 1.1673. 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 4.5 hours before apogee, the Moon's apparent diameter will be smaller.
This lunar eclipse will be the second of a tetrad, with four total lunar eclipses in series, the others being on March 4, 2072; February 22, 2073; and August 17, 2073.

Visibility

The eclipse will be completely visible over southeast and east Asia, Australia, and Antarctica, seen rising over Africa, Europe, and west and central Asia and setting over the eastern Pacific Ocean and western North America.

Eclipse season

This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months 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.

This eclipse is a member of a semester series. An eclipse in a semester series of lunar eclipses repeats approximately every 177 days and 4 hours at alternating nodes of the Moon's orbit.
The penumbral lunar eclipse on July 8, 2074 occurs in the next lunar year eclipse set.

Half-Saros cycle

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days. This lunar eclipse is related to two total solar eclipses of Solar Saros 136.
