May 29, 1919, Total Solar Eclipse: British, American and Brazilian Expeditions |
|
Abstract |
I report on the three expeditions organized to observe, in the Brazilian State of Ceará, the total solar eclipse in May 29, 1919. Apart from the well-known British expedition, which aimed to perform measurements of the bending of stellar light rays passing near the Sun, resulting in the confirmation of Einstein's Theory of General Relativity, there were two other expeditions in that occasion. One has been a Brazilian expedition, organized by the National Observatory, with the aim of studying the solar corona. The other has been a North-American expedition, organized by the Carnegie Institution, aiming to perform measurements related to terrestrial magnetism and atmospheric electricity. |
