A penumbral lunar eclipse will occur at the Moon’s ascending node of orbit on Thursday, January 21, 2038,[1] with an umbral magnitude of −0.1127. A lunar eclipse occurs when the Moon moves into the Earth's shadow, causing the Moon to be darkened. A penumbral lunar eclipse occurs when part or all of the Moon's near side passes into the Earth's penumbra. 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. Occurring about 3.1 days before perigee (on January 24, 2038, at 4:50 UTC), the Moon's apparent diameter will be larger.[2]
This eclipse will be the first of four penumbral lunar eclipses in 2038, with the others occurring on June 17, July 16, and December 11.

Visibility
The eclipse will be completely visible over North and South America, west Africa, and Europe, seen rising over the eastern Pacific Ocean and setting over east Africa and west and central Asia.[3]

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.

Lunar eclipses of 2035–2038
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 17, 2038 and December 11, 2038 occur in the next lunar year eclipse set.
Saros 144
This eclipse is a part of Saros series 144, repeating every 18 years, 11 days, and containing 71 events. The series started with a penumbral lunar eclipse on July 29, 1749. It contains partial eclipses from March 28, 2146 through June 23, 2290; total eclipses from July 4, 2308 through January 28, 2651; and a second set of partial eclipses from February 8, 2669 through June 8, 2867. The series ends at member 71 as a penumbral eclipse on September 4, 3011.
The longest duration of totality will be produced by member 38 at 104 minutes, 53 seconds on September 7, 2416. 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 series
This 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 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.
Half-Saros cycle
A 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 151.
