Solar eclipse of September 12, 1950

A total solar eclipse occurred on September 12, 1950. 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 eastern Soviet Union (today's Russia) and the whole Semichi Islands in Alaska.

Saros 124

Solar saros 124, repeating every about 18 years and 11 days, contains 73 events. The series started with partial solar eclipse on March 6, 1049. It contains total eclipses from June 12, 1211, to September 22, 1968, and a hybrid solar eclipse on October 3, 1986. The series ends at member 73 as a partial eclipse on May 11, 2347. The longest total eclipse occurred on May 3, 1734, at 5 minutes and 46 seconds.[2]

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.

22 eclipse events between September 12, 1931 and July 1, 2011.
