Solar eclipse of September 10, 1923

Total eclipse From Wikipedia, the free encyclopedia

Solar eclipse of September 10, 1923
Remove ads

A total solar eclipse occurred at the Moon's ascending node of orbit between Monday, September 10, and Tuesday, September 11, 1923,[1] with a magnitude of 1.043. 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. Occurring about 2.1 days before perigee (on September 12, 1923, at 23:20 UTC), the Moon's apparent diameter was larger.[2]

The path of totality started at the southeastern tip of Shiashkotan in Japan (now in Russia) on September 11, and crossed the Pacific Ocean, southwestern California including the whole Channel Islands, northwestern and northern Mexico, Yucatan Peninsula, British Honduras (today's Belize), Swan Islands in Honduras, and two outlying reefs in ColombiaSerranilla Bank and Bajo Nuevo, on September 10. The eclipse was over 90% in Los Angeles, San Diego, and Santa Barbara on the Southern California coast. A partial eclipse was visible for parts of far east Russia, northeastern Japan, North America, Central America, the Caribbean, and northern South America.

At Santa Catalina Island, off the coast of California, a large group of scientists gathered to observe the eclipse were foiled by clouds, with the Los Angeles Times saying that "nothing of the eclipse was seen save two glimpses that showed the crescent of the sun, a sickly, white watermelon rind with the wavering black moon and a few rags of black clouds fast blotting out the white light":[3]

All day the scientists from Yerkes Observatory of the University of Chicago, from the University of Wisconsin, from Dearborn University, from Drake University and Carleton College, had rehearsed and rehearsed to the counting of the seconds and there they stood now while the moon covered the sun and the world was dark and still, and though the counter counted there was no possibility of taking pictures; no chance of seeing anything but that gray, blue, purple shadow moving across the sky.[3]

Even as late as 11:30 when the eclipse began, the scientists had hopes. They had come thousands of miles, had worked hard, had spent much money, all for a few minutes of clear sky. They had worked in the sweltering sun for weeks and weeks 1302 feet above the sea. There had not been one moment of one day that was not flooded with sunshine. "And surely," said Prof. Edwin Frost of the University of Chicago, "surely we will have these few minutes today."[3]

In Bakersfield, where the last eclipse of the Sun had taken place 123 years earlier, many watched the eclipse from streets, chickens were confused, and "all the astronomical apparatus of Bakersfield" was trained on the eclipse.[4] In New York City the eclipse, while partial, was viewed successfully; in the area of totality, it was "studied by astronomers who [were] depending on it to help them test out Einstein's famous theory of relativity and whether light rays are bent by the attraction of gravity".[5]

A team from the University of Arizona took images of the corona in Puerto Libertad, Sonora, Mexico, on the east coast of the Gulf of California.[6] A team from Sproul Observatory observed it in Yerbanís in eastern Durango state, Mexico.[7]

Eclipse season

This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight.

Solar eclipses of 1921–1924

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.[9]

The partial solar eclipse on July 31, 1924 occurs in the next lunar year eclipse set.

Saros 143

This eclipse is a part of Saros series 143, repeating every 18 years, 11 days, and containing 72 events. The series started with a partial solar eclipse on March 7, 1617. It contains total eclipses from June 24, 1797 through October 24, 1995; hybrid eclipses from November 3, 2013 through December 6, 2067; and annular eclipses from December 16, 2085 through September 16, 2536. The series ends at member 72 as a partial eclipse on April 23, 2897. 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 16 at 3 minutes, 50 seconds on August 19, 1887, and the longest duration of annularity will be produced by member 51 at 4 minutes, 54 seconds on September 6, 2518. All eclipses in this series occur at the Moon’s ascending node of orbit.[10]

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 ascending node.

Tritos series

This eclipse is a part of a tritos cycle, repeating at alternating nodes every 135 synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee), but groupings of 3 tritos cycles (≈ 33 years minus 3 months) come close (≈ 434.044 anomalistic months), so eclipses are similar in these groupings.

Inex series

This eclipse is a part of the long period inex cycle, repeating at alternating nodes, every 358 synodic months (≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee). However, groupings of 3 inex cycles (≈ 87 years minus 2 months) comes close (≈ 1,151.02 anomalistic months), so eclipses are similar in these groupings.
