Solar eclipse of December 2, 1937

Summary

An annular solar eclipse occurred on December 2, 1937. 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 Ogasawara, Tokyo and South Seas Mandate (the part now belonging to Marshall Islands) in Japan, and Gilbert and Ellice Islands (the part now belonging to Kiribati).

The duration of annularity at maximum eclipse (closest to but slightly shorter than the longest duration) was 12 minutes, 0.33 seconds in the Pacific Ocean. It was the longest annular solar eclipse since December 25, 1628, but the Solar eclipse of December 14, 1955 lasted longer.[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]

Saros 141 edit

Solar saros 141, repeating every about 18 years, 11 days, and 8 hours, contains 70 events. The series started with partial solar eclipse on May 19, 1613. It contains 41 annular eclipses from August 4, 1739, to October 14, 2460. There are no total eclipses in this series. The series ends at member 70 as a partial eclipse on June 13, 2857. The longest annular eclipse occurred on December 14, 1955, with maximum duration of annularity at 12 minutes and 9 seconds. All eclipses in this series occur at the Moon’s ascending node.[3]

Series members 17–36 occur between 1901 and 2259

Tritos series edit

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.
