A partial solar eclipse occurred at the Moon's descending node of orbit on Wednesday, May 7, 1902,^[1]^[2]^[3] with a magnitude of 0.8593. 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 partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth.

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.^[4]

The partial solar eclipse on April 8, 1902 occurs in the next lunar year eclipse set.

Saros 146

This eclipse is a part of Saros series 146, repeating every 18 years, 11 days, and containing 76 events. The series started with a partial solar eclipse on September 19, 1541. It contains total eclipses from May 29, 1938 through October 7, 2154; hybrid eclipses from October 17, 2172 through November 20, 2226; and annular eclipses from November 30, 2244 through August 10, 2659. The series ends at member 76 as a partial eclipse on December 29, 2893. 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 26 at 5 minutes, 21 seconds on June 30, 1992, and the longest duration of annularity will be produced by member 63 at 3 minutes, 30 seconds on August 10, 2659. All eclipses in this series occur at the Moon’s descending node of orbit.^[5]

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.

The partial solar eclipse on October 24, 2098 (part of Saros 164) is also a part of this series but is not included in the table below.

Series members between 1801 and 2011
February 11, 1804 (Saros 137)	January 10, 1815 (Saros 138)	December 9, 1825 (Saros 139)	November 9, 1836 (Saros 140)	October 9, 1847 (Saros 141)
September 7, 1858 (Saros 142)	August 7, 1869 (Saros 143)	July 7, 1880 (Saros 144)	June 6, 1891 (Saros 145)	May 7, 1902 (Saros 146)
April 6, 1913 (Saros 147)	March 5, 1924 (Saros 148)	February 3, 1935 (Saros 149)	January 3, 1946 (Saros 150)	December 2, 1956 (Saros 151)

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.

Series members between 1801 and 2200
July 6, 1815 (Saros 143)	June 16, 1844 (Saros 144)	May 26, 1873 (Saros 145)
May 7, 1902 (Saros 146)	April 18, 1931 (Saros 147)	March 27, 1960 (Saros 148)
March 7, 1989 (Saros 149)	February 15, 2018 (Saros 150)	January 26, 2047 (Saros 151)

November 7, 2162 (Saros 155)	October 18, 2191 (Saros 156)
