Solar eclipse of May 28, 1900

A total solar eclipse occurred at the Moon's descending node of orbit on Monday, May 28, 1900,^[1][2] with a magnitude of 1.0249. 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 3.9 days after perigee (on May 24, 1900, at 17:30 UTC), the Moon's apparent diameter was larger.^[3]

The path of totality was visible from parts of Mexico, the states of Texas, Louisiana, Mississippi, Alabama, Georgia, South Carolina, North Carolina, and Virginia in the United States, Portugal, Spain, Algeria, Tripoli, and Egypt. A partial solar eclipse was also visible for parts of North America, Central America, the Caribbean, northern South America, Europe, West Africa, and North Africa.

Viewing

In 1900 the Smithsonian Astrophysical Observatory, then based in Washington, D.C., loaded several railroad cars with scientific equipment and headed to Wadesboro, North Carolina. Scientists had determined that this small town would be the best location in North America for viewing the total solar eclipse, and the Smithsonian Solar Eclipse Expedition hoped to capture photographic images of the solar corona during the event for further study.^[4] The team included Thomas Smillie, the mission's photographer. Smillie rigged cameras to seven telescopes and successfully made eight glass-plate negatives, ranging in size from eleven by fourteen inches to thirty by thirty inches. Smillie's work was considered an amazing photographic and scientific achievement.^[5]

In addition to the team from the Smithsonian:

[s]cientific expeditions were mounted from some of the world’s preeminent astronomy programs including Princeton University, the University of Chicago, . . . and the British Astronomical Association. S. P. Langley and C. A. Young, two of the founders of modern astronomy, were also there.

According to Wadesboro's newspaper, the Anson Independent, the public came out in droves. Extra trains—including a special excursion train from Charlotte—brought out hundreds of people, and by the time the eclipse’s effects were beginning to be seen around 7:30 a.m., the streets were packed, and people were vying for better spots from rooftops and windows..

The same local newspaper described the total eclipse itself as lasting for less than a minute and a half, and recorded that though a large crowd was on hand, it was nearly silent during that entire time. The paper also mentioned that the drop in temperature from the shadow caused by the eclipse was quite significant.^[4]

The eclipse was filmed by Nevil Maskelyne in North Carolina.^[6] It was also observed from Mahelma in Algeria by John Evershed.^[7]

Eclipse season

See also: Eclipse cycle

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 1898–1902

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 solar eclipses on January 22, 1898 (total) and July 18, 1898 (annular) occur in the previous lunar year eclipse set, and the partial solar eclipse on April 8, 1902 occurs in the next lunar year eclipse set.

Saros 126

This eclipse is a part of Saros series 126, repeating every 18 years, 11 days, and containing 72 events. The series started with a partial solar eclipse on March 10, 1179. It contains annular eclipses from June 4, 1323 through April 4, 1810; hybrid eclipses from April 14, 1828 through May 6, 1864; and total eclipses from May 17, 1882 through August 23, 2044. The series ends at member 72 as a partial eclipse on May 3, 2459. 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 annularity was produced by member 11 at 6 minutes, 30 seconds on June 26, 1359, and the longest duration of totality was produced by member 45 at 2 minutes, 36 seconds on July 10, 1972. All eclipses in this series occur at the Moon’s descending 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 descending 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.

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.
