A partial solar eclipse occurred at the Moon's ascending node of orbit on Wednesday, August 12, 1942, with a magnitude of 0.0561. 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 partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth. This was the 72nd of 72 solar eclipses in Saros 115 and the final eclipse.

Solar eclipses of 1942–1946[edit]

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.^[1]

The partial solar eclipses on March 16, 1942 and September 10, 1942 occur in the previous lunar year eclipse set, and the partial solar eclipses on May 30, 1946 and November 23, 1946 occur in the next lunar year eclipse set.

Saros 115[edit]

This eclipse is a part of Saros series 115, repeating every 18 years, 11 days, and containing 72 events. The series started with a partial solar eclipse on June 21, 662 AD. It contains total eclipses from October 7, 842 AD through November 2, 1491; hybrid eclipses from November 12, 1509 through December 15, 1563; and annular eclipses from December 25, 1581 through May 27, 1816. The series ends at member 72 as a partial eclipse on August 12, 1942. 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 totality was produced by member 36 at 6 minutes, 24 seconds on July 5, 1293, and the longest duration of annularity was produced by member 65 at 1 minutes, 54 seconds on May 27, 1816. All eclipses in this series occur at the Moon’s ascending node of orbit.^[2]

Series members 65–72 occur between 1801 and 1942:
65	66	67
May 27, 1816	June 7, 1834	June 17, 1852

Metonic series[edit]

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.
