An annular solar eclipse occurred at the Moon's ascending node of orbit on Sunday, August 1, 1943, with a magnitude of 0.9409. 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 25 minutes before apogee (on August 1, 1943, at 4:40 UTC), the Moon's apparent diameter was near its minimum. Apogee did occur as the eclipse was just before its greatest eclipse.
Annularity was visible in the southern Indian Ocean, with the only land being Île Amsterdam in French Madagascar (now belonging to French Southern and Antarctic Lands). A partial solar eclipse was visible from Australia, Indonesia, Malaysia, eastern Madagascar, Antarctica's Wilkes Land.

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.
