January 2037 lunar eclipse
A total lunar eclipse will occur at the Moon’s ascending node of orbit on Saturday, January 31, 2037,[1] with an umbral magnitude of 1.2086. 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 12 hours before perigee (on February 1, 2037, at 2:00 UTC), the Moon's apparent diameter will be larger.[2] This eclipse occurs during a supermoon and a blue moon (second full moon of month), of which the most recent occurrence was on January 31, 2018, one previous metonic cycle (19 years). VisibilityThe eclipse will be completely visible over east and northeast Asia, Australia, and northwestern North America, seen rising over west Asia, eastern Europe, and east Africa and setting over most of North America and the eastern Pacific Ocean.[3]
Eclipse detailsShown below is a table displaying details about this particular solar eclipse. It describes various parameters pertaining to this eclipse.[4]
Eclipse seasonThis 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 2035–2038This 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 17, 2038 and December 11, 2038 occur in the next lunar year eclipse set.
Saros 134This eclipse is a part of Saros series 134, repeating every 18 years, 11 days, and containing 72 events. The series started with a penumbral lunar eclipse on April 1, 1550. It contains partial eclipses from July 7, 1694 through October 13, 1856; total eclipses from October 25, 1874 through July 26, 2325; and a second set of partial eclipses from August 7, 2343 through November 12, 2505. The series ends at member 72 as a penumbral eclipse on May 28, 2830. The longest duration of totality will be produced by member 38 at 100 minutes, 23 seconds on May 22, 2217. All eclipses in this series occur at the Moon’s ascending node of orbit.[6]
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.
Tritos seriesThis eclipse is a part of a tritos cycle, repeating at alternating nodes every 135 synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee), but groupings of 3 tritos cycles (≈ 33 years minus 3 months) come close (≈ 434.044 anomalistic months), so eclipses are similar in these groupings.
Inex seriesThis 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.
Half-Saros cycleA lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[8] This lunar eclipse is related to two total solar eclipses of Solar Saros 141.
