Solar eclipse of February 25, 1952

Summary

A total solar eclipse occurred on February 25, 1952. 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. The path of totality crossed Africa, the Middle East, and Asia. [1][2][3][4][5]

Saros 139 edit

It is a part of saros series 139, repeating every 18 years, 11 days, 8 hours, containing 71 events. The series started with partial solar eclipse on May 17, 1501. It contains hybrid eclipses on August 11, 1627 through to December 9, 1825 and total eclipses from December 21, 1843 through to March 26, 2601. The series ends at member 71 as a partial eclipse on July 3, 2763. Its eclipses are entabulated in three columns; each one in the same column, every third eclipse, is one exeligmos apart so cast shadows over approximately the same parts of the Earth.

The solar eclipse of June 13, 2132 will be the longest total solar eclipse since July 11, 1991 at 6 minutes, 55.02 seconds.

The longest duration of totality will be produced by member 39 at 7 minutes, 29.22 seconds on July 16, 2186.[7] After that date each duration will decrease, until the series end. This date is the longest solar eclipse computed between 4000 BC and 6000 AD.[8] Saros series eclipses are during the Moon’s ascending node (a term related to our equator and polar-naming conventions).

Series members 24–45 occur between 1901 and 2300

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).
