An annular solar eclipse occurred on August 21, 1933. 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. Annularity was visible from 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), North Borneo (now belonging to Malaysia), and Australia.

Solar eclipses 1931–1935 edit

This eclipse is a member of a semester series. An eclipse in a semester series of solar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.^[1]

Saros 134 edit

It is a part of Saros cycle 134, repeating every 18 years, 11 days, containing 71 events. The series started with a partial solar eclipse on June 22, 1248. It contains total eclipses from October 9, 1428 through December 24, 1554 and hybrid eclipses from January 3, 1573 through June 27, 1843, and annular eclipses from July 8, 1861 through May 21, 2384. The series ends at member 71 as a partial eclipse on August 6, 2510. The longest duration of totality was 1 minutes, 30 seconds on October 9, 1428. All eclipses in this series occur at the Moon’s descending node.^[2]

Inex series edit

This eclipse is a part of the long period inex cycle, repeating at alternating nodes, every 358 synodic months (≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee). However, groupings of 3 inex cycles (≈ 87 years minus 2 months) comes close (≈ 1,151.02 anomalistic months), so eclipses are similar in these groupings. In the 18th century:

Solar Saros 127: Total Solar Eclipse of 1731 Jan 08
Solar Saros 128: Annular Solar Eclipse of 1759 Dec 19
Solar Saros 129: Annular Solar Eclipse of 1788 Nov 27
