A total solar eclipse occurred at the Moon's ascending node of orbit on Thursday, September 21, 1922,[1] with a magnitude of 1.0678.

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.

Occurring about 2 hours after perigee (on September 21, 1922, at 6:30 UTC), the Moon's apparent diameter was larger.

Observations of the total solar eclipse of May 29, 1919 got results consistent with gravitational lens proposed by Einstein's general relativity.

A total of 20 teams went to sparsely populated Wallal on the northern coast of Western Australia.

The team took a ship on August 20 from Fremantle, a port southwest of Perth, to Broome, and then finally arrived at Wallal.

Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee).
