Tritos series

The tritos series repeats 31 days short of 11 years at alternating nodes. Sequential events have incremental Saros cycle indices.

This series produces 20 total eclipses between April 24, 1967 and August 11, 2185, only being partial on November 19, 2021.

Saros series

Lunar saros series 128, repeating every 18 years and 11 days, has a total of 71 lunar eclipse events including 57 umbral eclipses (42 partial lunar eclipses and 15 total lunar eclipses). Solar Saros 135 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.

Lunar Saros 128 contains 15 total lunar eclipses between 1845 and 2097 (in years 1845, 1863, 1881, 1899, 1917, 1935, 1953, 1971, 1989, 2007, 2025, 2043, 2061, 2079 and 2097). Solar Saros 135 interleaves with this lunar saros with an event occurring every 9 years 5 days alternating between each saros series.

Half-Saros cycle

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).^[4] This lunar eclipse is related to two annular solar eclipses of Solar Saros 135.
