Solar eclipse of July 31, 1962 explained

An annular solar eclipse occurred at the Moon's ascending node of orbit on Tuesday, July 31, 1962,[1] with a magnitude of 0.9716. 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. Occurring about 4.75 days before apogee (on August 5, 1962, at 6:40 UTC), the Moon's apparent diameter was smaller.[2]

Places inside the annular eclipse included Venezuela, northern Roraima in Brazil, Guyana, Dutch Guiana (today's Suriname) including the capital city Paramaribo, Senegal, Gambia Colony and Protectorate (today's Gambia) including the southern part of the capital city Banjul, Mali including the capital city Bamako, Upper Volta (today's Burkina Faso), Ghana, Togo, Dahomey (today's Benin), Nigeria, Cameroon including the capital city Yaoundé, Congo-Brazzaville, Congo-Léopoldville (today's DR Congo), Tanganyika (now belonging to Tanzania), northeastern tip of Portuguese Mozambique (today's Mozambique), French Comoros (today's Comoros), Mayotte, and the Malagasy Republic (today's Madagascar). The greatest eclipse was in the area of Kouoro, Mali at 12 N, 5.7 W at 12:25 (UTC) and lasted for 3 minutes.[3] A partial eclipse was visible for parts of the Caribbean, northern South America, Africa, Southern Europe, and the Middle East.

Eclipse season

See also: Eclipse cycle. This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight. The first and last eclipse in this sequence is separated by one synodic month.
