Solar eclipse of February 4, 1943

A total solar eclipse occurred on February 4–5, 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 5th (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 4th (Thursday) over Alaska and Yukon in Canada.

Solar eclipses 1942–1946

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]

Note: The partial solar eclipse on September 10, 1942 occurs in the previous lunar year eclipse set.

Saros 120

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

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.
