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]

This eclipse is a part of Saros series 119, repeating every 18 years, 11 days, and containing 71 events. The series started with a partial solar eclipse on May 15, 850 AD. It contains total eclipses on August 9, 994 AD and August 20, 1012; a hybrid eclipse on August 31, 1030; and annular eclipses from September 10, 1048 through March 18, 1950. The series ends at member 71 as a partial eclipse on June 24, 2112. 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 10 at 32 seconds on August 20, 1012, and the longest duration of annularity was produced by member 44 at 7 minutes, 37 seconds on September 1, 1625. All eclipses in this series occur at the Moon’s ascending node of orbit.^[4]

Series members 54–71 occur between 1801 and 2112:

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 ascending node.

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.

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.
