In-game article clicks load inline without leaving the challenge.
A partial solar eclipse occurred at the Moon's descending node of orbit on Tuesday, September 8, 1801, with a magnitude of 0.1614. 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.
The partial solar eclipse was visible for parts of modern-day eastern Russia and western Alaska.

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 1801–1805
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 April 13, 1801 and October 7, 1801 occur in the previous lunar year eclipse set, and the solar eclipses on January 1, 1805 (partial); June 26, 1805 (partial); and December 21, 1805 (annular) occur in the next lunar year eclipse set.

Saros 112
This eclipse is a part of Saros series 112, repeating every 18 years, 11 days, and containing 72 events. The series started with a partial solar eclipse on July 31, 539 AD. It contains total eclipses from March 15, 918 AD through November 18, 1332; hybrid eclipses from November 30, 1350 through April 29, 1585; and annular eclipses from May 11, 1603 through June 23, 1675. The series ends at member 72 as a partial eclipse on September 19, 1819. 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 30 at 7 minutes, 20 seconds on June 9, 1062, and the longest duration of annularity was produced by member 64 at 1 minute, 1 second on June 23, 1675. 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.

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.
