January 2048 lunar eclipse

A total lunar eclipse will occur at the Moon’s descending node of orbit on Wednesday, January 1, 2048,^[1] with an umbral magnitude of 1.1297. 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 4.4 days after apogee (on December 27, 2047, at 21:50 UTC), the Moon's apparent diameter will be smaller.^[2]

This will be the first recorded lunar eclipse to be visible on New Year's Day for nearly all of Earth's timezones. The next such eclipse will occur in 2094.

Visibility

The eclipse will be completely visible over North America and western South America, seen rising over east and northeast Asia and eastern Australia and setting over much of Africa and Europe.^[3]

Eclipse season

See also: Eclipse cycle

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 2046–2049

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 May 17, 2049 and November 9, 2049 occur in the next lunar year eclipse set.

Saros 135

This eclipse is a part of Saros series 135, repeating every 18 years, 11 days, and containing 71 events. The series started with a penumbral lunar eclipse on April 13, 1615. It contains partial eclipses from July 20, 1777 through October 28, 1939; total eclipses from November 7, 1957 through July 6, 2354; and a second set of partial eclipses from July 16, 2372 through September 19, 2480. The series ends at member 71 as a penumbral eclipse on May 18, 2877.

The longest duration of totality will be produced by member 37 at 106 minutes, 13 seconds on May 12, 2264. All eclipses in this series occur at the Moon’s descending node of orbit.^[6]

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.
