A penumbral lunar eclipse will occur at the Moon’s descending node of orbit on Thursday, July 6, 1944,^[1] with an umbral magnitude of −0.4398. 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 2.8 days before perigee (on July 8, 1944, at 23:40 UTC), the Moon's apparent diameter was larger.^[2]

This eclipse was the second of four penumbral lunar eclipses in 1944, with the others occurring on February 9, August 4, and December 29.

Visibility

The eclipse was completely visible over much of North America, South America, and Antarctica, seen rising over northwestern North America and the central Pacific Ocean and setting over western Europe and Africa.^[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. The first and last eclipse in this sequence is separated by one synodic month.

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 116.
