Template:Short description Script error: No such module "Solar eclipse". An annular solar eclipse occurred at the Moon's ascending node of orbit between Thursday, December 2 and Friday, December 3, 1937,[1] with a magnitude of 0.9184. 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 18 hours before apogee (on December 3, 1937, at 16:50 UTC), the Moon's apparent diameter was smaller.[2]

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.[3]

Annularity was visible from outlying islands in Japan on December 3, including part of Ogasawara Village and South Seas Mandate (the part now belonging to Marshall Islands), and also Teraina and Tabuaeran in the Gilbert and Ellice Islands (the part now belonging to Kiribati), a colony of the United Kingdom, on December 2. (However, time zone of the Line Islands including Teraina and Tabuaeran was changed from UTC−10 to UTC+14 in 1995. The date would be December 3 for all annular eclipse visible from land if observing the present day's time zone.)

A partial eclipse was visible for parts of East Asia, northern Oceania, Hawaii, and western North America. Part of these areas are east of the 180th meridian, seeing the eclipse on December 2, and the rest west of the 180th meridian, seeing the eclipse on December 3.

Eclipse season

Script error: No such module "Labelled list hatnote". 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.

Solar eclipses of 1935–1938

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.[5]

The partial solar eclipses on February 3, 1935 and July 30, 1935 occur in the previous lunar year eclipse set.

Saros 141

This eclipse is a part of Saros series 141, repeating every 18 years, 11 days, and containing 70 events. The series started with a partial solar eclipse on May 19, 1613. It contains annular eclipses from August 4, 1739 through October 14, 2640. There are no hybrid or total eclipses in this set. The series ends at member 70 as a partial eclipse on June 13, 2857. Its eclipses are tabulated in three columns; every third eclipse in the same column is one exeligmos apart, so they all cast shadows over approximately the same parts of the Earth.

The longest duration of annularity was produced by member 20 at 12 minutes, 9 seconds on December 14, 1955. All eclipses in this series occur at the Moon’s ascending node of orbit.[6]

Series members 12–33 occur between 1801 and 2200:
