An annular solar eclipse occurred on July 31, 1962. 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 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.[1]

This eclipse is a member of a semester series. An eclipse in a semester series of solar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.[2]
The partial solar eclipses on June 10, 1964 and December 4, 1964 occur in the next lunar year eclipse set.

Inex series
This eclipse is a part of the long period inex cycle, repeating at alternating nodes, every 358 synodic months (≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee). However, groupings of 3 inex cycles (≈ 87 years minus 2 months) comes close (≈ 1,151.02 anomalistic months), so eclipses are similar in these groupings.

Metonic series
The metonic series repeats eclipses every 19 years (6939.69 days), lasting about 5 cycles. Eclipses occur in nearly the same calendar date. In addition, the octon subseries repeats 1/5 of that or every 3.8 years (1387.94 days). All eclipses in this table occur at the Moon's ascending node.
