An annular solar eclipse occurred at the Moon's ascending node of orbit on Thursday, July 20, 1944, with a magnitude of 0.97. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Occurring about 4.6 days before apogee (on July 24, 1944, at 19:20 UTC), the Moon's apparent diameter was smaller.

Annularity was visible from British Uganda (today's Uganda), Anglo-Egyptian Sudan (the part now belonging to South Sudan), British Kenya (today's Kenya), Ethiopia, British Somaliland (today's Somalia), British Raj (the part now belonging to India), Burma under Japanese occupation (today's Myanmar), Thailand, French Indochina (the parts now belonging to Laos and Vietnam), Philippines under Japanese occupation, South Seas Mandate in Japan (the part now belonging to Hatohobei, Palau) the Territory of New Guinea (now belonging to Papua New Guinea). A partial eclipse was visible for parts of East Africa, West Asia, Central Asia, South Asia, Southeast Asia, East Asia, and Australia.

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.
