• Source: Solar eclipse of April 8, 1902

A partial solar eclipse occurred at the Moon's descending node of orbit on Tuesday, April 8, 1902, 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.
A partial eclipse was visible for parts of Northern Canada. This was the 76th and final event from Solar Saros 108.




Eclipse details


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.




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. The first and last eclipse in this sequence is separated by one synodic month.

= Solar eclipses of 1902–1906

=
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.
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

=
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.




= 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 eclipses on April 8, 1902 (part of Saros 108) and January 5, 1935 (part of Saros 111) are also a part of this series but are not included in the table below.
