Solar eclipse of February 4, 1943

Summary

A total solar eclipse occurred between Thursday, February 4 and Friday, February 5, 1943. 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. It began on the morning on February 5 (Friday) over northeastern China (then occupied by Manchukuo), Primorsky Krai in the Soviet Union (now Russia), Hokkaido and southern Kunashir Island in Japan (Kunashir now belonging to Russia) and ended at sunset on February 4 (Thursday) over Alaska and Yukon in Canada.

Saros 120 edit

This eclipse is a part of Saros cycle 120, repeating every 18 years, 11 days, containing 71 events. The series started with partial solar eclipse on May 27, 933 AD, and reached an annular eclipse on August 11, 1059. It was a hybrid event for 3 dates: May 8, 1510, through May 29, 1546, and total eclipses from June 8, 1564, through March 30, 2033. The series ends at member 71 as a partial eclipse on July 7, 2195. The longest duration of totality was 2 minutes, 50 seconds on March 9, 1997. All eclipses in this series occurs at the Moon’s descending node.

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 descending node.

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