Solar eclipse of May 29, 1919


A total solar eclipse occurred on May 29, 1919. With the duration of totality at maximum eclipse of 6 minutes 50.75 seconds, it was the longest solar eclipse since May 27, 1416. A longer total solar eclipse would later occur on June 8, 1937.
Occurring only 0.8 days after perigee, the Moon's apparent diameter was larger.
It was visible throughout most of South America and Africa as a partial eclipse. Totality occurred through a narrow path across southeastern Peru, northern Chile, central Bolivia and Brazil after sunrise, across the Atlantic Ocean and into south central Africa, covering southern Liberia, southern French West Africa, southwestern tip of British Gold Coast, Príncipe Island in Portuguese São Tomé and Príncipe, southern Spanish Guinea, French Equatorial Africa, Belgian Congo, northeastern Northern Rhodesia, northern tip of Nyasaland, German East Africa and northeastern Portuguese Mozambique, ending near sunset in eastern Africa. There was another solar eclipse in 1919, an annular solar eclipse on November 22.

Observations

Albert Einstein's prediction of the bending of light by the gravity of the Sun, one of the components of his general theory of relativity, can be tested during a solar eclipse, when stars with apparent position near the sun become visible. Following an unsuccessful attempt to validate this prediction during the Solar eclipse of June 8, 1918, two expeditions were made to measure positions of stars during this eclipse. The first was led by Sir Frank Watson Dyson and Sir Arthur Eddington to the island of Príncipe, the second by Andrew Claude de la Cherois Crommelin and Charles Rundle Davidson to Sobral in Brazil. The stars that both expeditions observed were in the constellation Taurus.
