A total solar eclipse occurred at the Moon's descending node of orbit on Sunday, December 22, 1889, with a magnitude of 1.0449. 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 12.5 hours before perigee (on December 23, 1889, at 1:30 UTC), the Moon's apparent diameter was larger. ^[1]

The path of totality was visible from parts of modern-day Trinidad and Tobago, northern French Guiana, Angola, the Democratic Republic of the Congo, Rwanda, Burundi, Tanzania, Kenya, and Somalia. A partial solar eclipse was also visible for parts of the eastern Caribbean, northern and central South America, and Africa.

The eclipse was the focus of a 242-day United States scientific expedition, roughly 70 miles south of Luanda.

Observations

The eclipse was the focus of a scientific expedition from the United States, led by David P. Todd of Amherst College and including a team of at least six. Among the members was E. J. Loomis from the American Ephemeris and Nautical Almanac office. It set sail October 16 on the USS Pensacola and set up the eclipse base camp in December, roughly 70 miles south of Luanda in Cape Ledo. Totality was completely obscured by cloud cover. The ship returned to New York after 242 days, with the expedition performing a variety of other scientific studies along the way. ^{[2] [3]}

The 1889 solar eclipse was the last to be photographed by Stephen Joseph Perry.

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 1888–1891

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. ^[5]

The partial solar eclipses on February 11, 1888 and August 7, 1888 occur in the previous lunar year eclipse set.

Saros 130

This eclipse is a part of Saros series 130, repeating every 18 years, 11 days, and containing 73 events. The series started with a partial solar eclipse on August 20, 1096. It contains total eclipses from April 5, 1475 through July 18, 2232. There are no annular or hybrid eclipses in this set. The series ends at member 73 as a partial eclipse on October 25, 2394. 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 30 at 6 minutes, 41 seconds on July 11, 1619. All eclipses in this series occur at the Moon’s descending node of orbit. ^[6]

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.

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.
