An annular solar eclipse occurred at the Moon's descending node of orbit on Monday, August 21, 1933, with a magnitude of 0.9801. 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 only 5.6 days after apogee (on August 15, 1933, at 15:40 UTC), the Moon's apparent diameter was smaller.
Annularity was visible from a small tip of northeastern Italian Libya (today's Libya), Egypt, Mandatory Palestine (today's Israel, Palestine and Jordan) including Jerusalem and Amman, French Mandate for Syria and the Lebanon (the part now belonging to Syria), Iraq including Baghdad, Persia, Afghanistan, British Raj (the parts now belonging to Pakistan, India, Bangladesh and Myanmar), Siam (name changed to Thailand later), Dutch East Indies (today's Indonesia), Raj of Sarawak (now belonging to Malaysia), and Australia. A partial eclipse was visible for parts of Northeast Africa, Eastern Europe, 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.
