An annular solar eclipse occurred at the Moon's descending node of orbit on Tuesday, March 28, 1922, with a magnitude of 0.9381. 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 2.75 days after apogee (on March 25, 1922, at 19:30 UTC), the Moon's apparent diameter was smaller.
Annularity was visible from Peru, Brazil, French West Africa (parts now belonging to Senegal, Mauritania and Mali), British Gambia (today's Gambia) including capital Banjul, French Algeria (today's Algeria), Italian Libya (today's Libya), Egypt, Kingdom of Hejaz and Sultanate of Nejd (now belonging to Saudi Arabia), and Sheikhdom of Kuwait (today's Kuwait). A partial eclipse was visible for parts of South America, the Caribbean, North Africa, Central Africa, Europe, and the Middle East.

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.
