A total solar eclipse occurred on September 21, 1922.

This eclipse started in Africa and covered the whole Indian Ocean and Australia. Two large scientific expeditions investigated Einstein's theory of relativity.^[1]

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.
