A total lunar eclipse will occur at the Moon’s ascending node of orbit on Wednesday, September 7, 2044,[1] with an umbral magnitude of 1.0456. 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 5.8 days after apogee (on September 1, 2044, at 16:30 UTC), the Moon's apparent diameter will be smaller.[2]

This lunar eclipse is the last of a tetrad, with four total lunar eclipses in series, the others being on March 25, 2043; September 19, 2043; and March 13, 2044.

This eclipse will also be the first total eclipse of Lunar Saros 138.

Visibility

The eclipse will be completely visible over eastern Australia, northeast Asia, and northwestern North America, seen rising over much of Asia and western Australia and setting over much of North and South America.[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.

Metonic series

The Metonic cycle repeats nearly exactly every 19 years and represents a Saros cycle plus one lunar year. Because it occurs on the same calendar date, the Earth's shadow will in nearly the same location relative to the background stars.

  1. 2006 Mar 14.99 - penumbral (113)
  2. 2025 Mar 14.29 - total (123)
  3. 2044 Mar 13.82 - total (133)

  3. 2044 Sep 07.47 - partial (138)
  4. 2063 Sep 07.86 - penumbral (148)

Half-Saros cycle

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[5] This lunar eclipse is related to two total solar eclipses of Solar Saros 145.
