Eclipses of 2019

Lunar year series

This eclipse is a member of a semester series. An eclipse in a semester series of lunar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.[2]

The penumbral lunar eclipses on March 23, 2016 and September 16, 2016 occur in the previous lunar year eclipse set, and the penumbral lunar eclipses on June 5, 2020 and November 30, 2020 occur in the next lunar year eclipse set.

Saros cycle

This eclipse is a part of Saros series 139, repeating every 18 years, 11 days, and containing 79 events. The series started with a penumbral lunar eclipse on December 9, 1658. It contains partial eclipses from June 3, 1947 through August 7, 2055; total eclipses from August 17, 2073 through May 30, 2542; and a second set of partial eclipses from June 9, 2560 through August 25, 2686. The series ends at member 75 as a penumbral eclipse on April 13, 3065.

The longest duration of totality will be produced by member 31 at 102 minutes, 39 seconds on November 2, 2199. All eclipses in this series occur at the Moon’s descending node of orbit.[3]

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.

Half-Saros cycle

A lunar eclipse will be preceded and followed by solar eclipses by 9 years and 5.5 days (a half saros).[5] This lunar eclipse is related to two total solar eclipses of Solar Saros 146.
