Solar eclipses of 2040–2043
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.[1]

Saros 139
This eclipse is a member of saros series 139, repeating every 18 years, 11 days, 8 hours, containing 71 events. The series started with partial solar eclipse on May 17, 1501. It contains hybrid eclipses on August 11, 1627, through to December 9, 1825; and total eclipses from December 21, 1843, through to March 26, 2601. The series ends at member 71 as a partial eclipse on July 3, 2763. 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
The longest duration of totality will be produced by member 39 at 7 minutes, 29.22 seconds on July 16, 2186.[2] After that date, the durations of totality will decrease until the series ends. This date is the longest solar eclipse computed between 4000 BC and AD 6000.[3] Saros series eclipses occur during the Moon's ascending node (a term related to our equator and polar-naming conventions).

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.

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 ascending node.
