January 2084 lunar eclipse
Template:Short description Template:Infobox lunar eclipse A total lunar eclipse will occur at the Moon’s descending node of orbit on Saturday, January 22, 2084,[1] with an umbral magnitude of 1.1531. 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 days after apogee (on January 18, 2084, at 23:50 UTC), the Moon's apparent diameter will be smaller.[2]
This lunar eclipse will be the third of an almost tetrad, with the others being on February 2, 2083 (total); July 29, 2083 (total); and July 17, 2084 (partial).
Visibility
The eclipse will be completely visible over Africa, Europe, and west and central Asia, seen rising over North and South America and setting over south and east 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.

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.

Inex series
This eclipse is a part of the long period inex cycle, repeating at alternating nodes, every 358 synodic months (≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee). However, groupings of 3 inex cycles (≈ 87 years minus 2 months) comes close (≈ 1,151.02 anomalistic months), so eclipses are similar in these groupings.
