July 2083 lunar eclipse
Template:Short description Template:Infobox lunar eclipse A total lunar eclipse will occur at the Moon’s ascending node of orbit on Thursday, July 29, 2083,[1] with an umbral magnitude of 1.4791. It will be a central lunar eclipse, in which part of the Moon will pass through the center of the Earth's shadow. 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 2.9 days after perigee (on July 26, 2083, at 2:25 UTC), the Moon's apparent diameter will be larger.[2]
This lunar eclipse will be the second of an almost tetrad, with the others being on February 2, 2083 (total); January 22, 2084 (total); and July 17, 2084 (partial).
This will be the last central lunar eclipse of Lunar Saros 130.
Visibility
The eclipse will be completely visible over much of South America, Africa, western Europe, and Antarctica, seen rising over North America and the eastern Pacific Ocean and setting over eastern Europe, the western half of Asia, and western Australia.[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. The first and last eclipse in this sequence is separated by one synodic month.

Lunar eclipses of 2082–2085
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 (a semester) at alternating nodes of the Moon's orbit.[5]
The penumbral lunar eclipses on June 8, 2085 and December 1, 2085 occur in the next lunar year eclipse set.

Eclipses are tabulated in three columns; every third eclipse in the same column is one exeligmos apart, so they all cast shadows over approximately the same parts of the Earth.
