Solar eclipse of November 1, 1948

A total solar eclipse occurred on November 1, 1948. 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. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. Totality was visible from Belgian Congo (today's DR Congo), Uganda Protectorate (today's Uganda) including the capital city Kampala, British Kenya (today's Kenya) including the capital city Nairobi, British Seychelles (today's Seychelles), and British Mauritius (today's Mauritius). During this eclipse, comet C/1948 V1, also known as the Eclipse Comet of 1948, was discovered shining near the sun.[1]

Solar eclipses 1946–1949

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]

Saros series 142

It is a part of Saros cycle 142, repeating every 18 years, 11 days, containing 72 events. The series started with partial solar eclipse on April 17, 1624. It contains one hybrid eclipse on July 14, 1768, and total eclipses from July 25, 1786 through October 29, 2543. The series ends at member 72 as a partial eclipse on June 5, 2904. The longest duration of totality will be 6 minutes, 34 seconds on May 28, 2291. All eclipses in this series occurs at the Moon’s descending node.[3]

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.

Tritos series

This eclipse is a part of a tritos cycle, repeating at alternating nodes every 135 synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee), but groupings of 3 tritos cycles (≈ 33 years minus 3 months) come close (≈ 434.044 anomalistic months), so eclipses are similar in these groupings.
