An annular solar eclipse occurred on March 17, 1923. 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. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Annularity was visible from Chile, Argentina, Falkland Islands including capital Stanley, Gough Island in Tristan da Cunha, South West Africa (today's Namibia), Bechuanaland Protectorate (today's Botswana, Southern Rhodesia (today's Zimbabwe) including capital Salisbury, Portuguese Mozambique (today's Mozambique), Nyasaland (today's Malawi), French Madagascar (the part now belonging to Madagascar, and the Islands of Juan de Nova and Tromelin).
