Solar eclipse of February 25, 1914
20th-century annular solar eclipse From Wikipedia, the free encyclopedia
An annular solar eclipse occurred at the Moon's ascending node of orbit between Tuesday, February 24 and Wednesday, February 25, 1914,[1][2][3] with a magnitude of 0.9248. 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. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Occurring about 3.3 days before apogee (on February 28, 1914, at 9:10 UTC), the Moon's apparent diameter was smaller.[4]
It took place almost entirely over the Southern Ocean, near Antarctica;[2] at its widest, the shadow cast by the moon was 167 mi (269 km) wide.[2] As a result, it could be seen from small patches of land, most notably southern Patagonia and part of New Zealand.[2][3][5] Due to this limited visibility, the Star-Gazette of Elmira said that for readers in the United States it was "not particularly interesting from a popular perspective";[6] the Salina Daily Union in Salina, Kansas said that "you perhaps didn't notice it".[7] It was the first of four eclipses that occurred during the year 1914.[3][5] While its path passed over New Zealand, and some attempted to view it in Wellington, it was reported to not have been visible there due to cloud cover.[8][9]

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 1913–1917
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.[11]
The partial solar eclipses on April 6, 1913 and September 30, 1913 occur in the previous lunar year eclipse set, and the solar eclipses on December 24, 1916 (partial), June 19, 1917 (partial), and December 14, 1917 (annular) occur in the next lunar year eclipse set.

Saros 119
This eclipse is a part of Saros series 119, repeating every 18 years, 11 days, and containing 71 events. The series started with a partial solar eclipse on May 15, 850 AD. It contains total eclipses on August 9, 994 AD and August 20, 1012; a hybrid eclipse on August 31, 1030; and annular eclipses from September 10, 1048 through March 18, 1950. The series ends at member 71 as a partial eclipse on June 24, 2112. 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 10 at 32 seconds on August 20, 1012, and the longest duration of annularity was produced by member 44 at 7 minutes, 37 seconds on September 1, 1625. All eclipses in this series occur at the Moon’s ascending node of orbit.[12]

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.
