Solar eclipse of November 23, 1965

20th-century annular solar eclipse


An annular solar eclipse occurred on November 23, 1965. 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 the Soviet Union (today's eastern Turkmenistan, southern Uzbekistan and southwestern Tajikistan), Afghanistan, Pakistan, India, China, Nepal (including the capital city Kathmandu), southwestern Sikkim (now merged with India), Burma, southwestern tip of Sainyabuli Province in Laos, Cambodia, South Vietnam (now belonging to Vietnam), Spratly Islands, Brunei, Malaysia, Indonesia, the Territory of Papua New Guinea (today's Papua New Guinea), and Gilbert and Ellice Islands (the part now belonging to Kiribati). 8 of the 14 eight-thousandersDhaulagiri, Annapurna, Manaslu, Shishapangma, Cho Oyu, Everest, Lhotse and Makalu, as well as the highest peak of Oceania, Puncak Jaya, lie in the path of annularity.

Observation

An observation team of the Lockheed Corporation and the United States Air Force observed the annular eclipse near Chiang Mai, Thailand's second largest city. They calculated the relationship between the angular diameters of the moon and the sun during annularity, and the flattening of the moon based on the results[1].

Solar eclipses of 1964–1967

This eclipse is a member of a 1964–1967 series at alternating nodes every 6 synodic months.

Note: Partial solar eclipses on January 14, 1964 and July 9, 1964 belong to the previous lunar year set.

Saros 132

This eclipse is a part of Saros cycle 132, repeating every 18 years, 11 days, containing 71 events. The series started with partial solar eclipse on August 13, 1208. It contains annular eclipses from March 17, 1569 through March 12, 2146, hybrid on March 22, 2164 and April 3, 2182 and total eclipses from April 14, 2200 through June 19, 2308. The series ends at member 71 as a partial eclipse on September 25, 2470. The longest duration of annularity was 6 minutes, 56 seconds on May 9, 1641, and totality will be 2 minutes, 14 seconds on June 8, 2290. All eclipses in this series occurs at the Moon’s descending node.

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 descending node.
