A partial solar eclipse occurred at the Moon's descending node of orbit on Tuesday, April 8, 1902,^[1]^[2] with a magnitude of 0.0643. 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. This was the 76th and final event from Solar Saros 108.

Solar eclipses of 1902–1906[edit]

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.^[3]

The partial solar eclipses on May 7, 1902 and October 31, 1902 occur in the previous lunar year eclipse set, and the partial solar eclipse on July 21, 1906 occurs in the next lunar year eclipse set.

Saros 108[edit]

This eclipse is a part of Saros series 108, repeating every 18 years, 11 days, and containing 76 events. The series started with a partial solar eclipse on January 4, 550 AD. It contains annular eclipses from May 13, 766 AD through December 4, 1108; hybrid eclipses from December 15, 1126 through January 28, 1199; and total eclipses from February 7, 1217 through August 11, 1523. The series ends at member 76 as a partial eclipse on April 8, 1902. 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 13 at 3 minutes, 35 seconds on May 13, 766 AD, and the longest duration of totality was produced by member 46 at 5 minutes, 7 seconds on May 5, 1361. All eclipses in this series occur at the Moon’s descending node of orbit.^[4]

Series members 71–76 occur between 1801 and 1902:
71	72	73
February 12, 1812	February 23, 1830	March 5, 1848
74	75	76
March 16, 1866	March 27, 1884	April 8, 1902

Metonic series[edit]

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).

22 eclipse events, progressing from north to south between April 8, 1902, and August 31, 1989:
April 7–8	January 24–25	November 12	August 31-September 1	June 19–20
