A total solar eclipse occurred on September 21, 1922. 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. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. The greatest eclipse occurred exactly at perigee.

Totality started in Ethiopia, Italian Somaliland (today's Somalia), and passed British Maldives and Christmas Island in the Straits Settlements (now in Australia) in the Indian Ocean, and Australia.

Observations

Observations of the total solar eclipse of May 29, 1919 got results consistent with gravitational lens proposed by Einstein's general relativity. To reconfirm the result, observatories in South Australia and New South Wales each organized a large scientific expedition. A total of 20 teams went to sparsely populated Wallal on the northern coast of Western Australia. Among them, the American team from the Lick Observatory arrived in Sydney on August 5, took a train westward and arrived in Perth on August 16. The team took a ship on August 20 from Fremantle, a port southwest of Perth, to Broome, and then finally arrived at Wallal. Although not organizing any observations, the Australian government provided financial support to the teams. For example, the round-trip travel expenses between Sydney and Wallal were paid by the federal government [1] [2] .

Solar eclipses 1921–1924

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. [3]

Saros 133

Solar Saros 133, repeating every 18 years, 11 days, contains 72 events. The series started with a partial solar eclipse on July 13, 1219. It contains annular eclipses from November 20, 1435, through January 13, 1526, with a hybrid eclipse on January 24, 1544. It has total eclipses from February 3, 1562, through June 21, 2373. The series ends at member 72 as a partial eclipse on September 5, 2499. The longest duration of totality was 6 minutes, 49.97 seconds on August 7, 1850. [4] The total eclipses of this saros series are getting shorter and farther south with each iteration. All eclipses in this series occurs at the Moon’s ascending node.

Series members 30–56 occur between 1742 and 2211
