A partialsolar eclipse occurred at the Moon'sascending node of orbit on Friday, October 31, 1902,[1][2] with amagnitude of 0.696. Asolar eclipse occurs when theMoon passes betweenEarth and theSun, 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.
A partial eclipse was visible for parts ofNorthern Europe,Eastern Europe, the northernMiddle East,South Asia,East Asia, andNorth Asia.
Shown below are two tables displaying details about this particular solar eclipse. The first table outlines times at which the Moon's penumbra or umbra attains the specific parameter, and the second table describes various other parameters pertaining to this eclipse.[3]

This eclipse is part of aneclipse 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 afortnight.

This eclipse is a member of asemester series. An eclipse in a semester series of solar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternatingnodes of the Moon's orbit.[4]
The solar eclipses onJanuary 22, 1898 (total) and July 18, 1898 (annular) occur in the previous lunar year eclipse set, and the partial solar eclipse onApril 8, 1902 occurs in the next lunar year eclipse set.

This eclipse is a part ofSaros series 151, repeating every 18 years, 11 days, and containing 72 events. The series started with a partial solar eclipse on August 14, 1776. It contains annular eclipses from February 28, 2101 through April 23, 2191; a hybrid eclipse on May 5, 2209; and total eclipses from May 16, 2227 through July 6, 2912. The series ends at member 72 as a partial eclipse on October 1, 3056. Its eclipses are tabulated in three columns; every third eclipse in the same column is oneexeligmos apart, so they all cast shadows over approximately the same parts of the Earth.
The longest duration of annularity will be produced by member 19 at 2 minutes, 44 seconds on February 28, 2101, and the longest duration of totality will be produced by member 60 at 5 minutes, 41 seconds on May 22, 2840. All eclipses in this series occur at the Moon’sascending node of orbit.[5]

Themetonic 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.

This eclipse is a part of atritos cycle, repeating at alternating nodes every 135synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with theanomalistic 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.
