The Saturday, Aug. 4, 1906, total lunar eclipse belongs to Saros cycle 127, which comprises 72 lunar eclipses displaying similar geometries.
The lunar Saros cycle groups lunar eclipses into families, known as series, according to such similar geometries as occurrence at the same lunar node. The ascending and descending nodes represent the two points of intersection of the moon's orbit with Earth's orbit. The moon exhibits southward movement away from the ascending node and northward movement away from the descending node.
All lunar eclipses in lunar Saros cycle 127 occur at the moon's descending node. As such, each successive eclipse in the Saros cycle 127 lineup of 72 lunar eclipses progresses northward.
A Saros cycle equates to approximately 6,585.3 days (18 years 11 days 8 hours). Specifically, Saros cycle 127 has a duration of 1,280.14 years, according to NASA (National Aeronautics and Space Administration) Eclipse Web Site's eclipse predictions by NASA astrophysicist, now retired, Fred Espenak. Saros cycle 127 covers 14 centuries, beginning in the 13th century and finishing in the 26th century.
The Saros cycle 127 comprises 18 penumbral lunar eclipses, 38 partial lunar eclipses and 16 total lunar eclipses. The 72 lunar eclipses in Saros cycle 127 sequence as five, same-eclipse sets. The first set contains 11 penumbral lunar eclipses. The second set comprises 18 partial lunar eclipses. The third set is composed of 16 total lunar eclipses. The fourth set features the last 20 of Saros cycle 127's 38 partial lunar eclipses. The fifth set offers the last seven of Saros cycle 127's 18 penumbral lunar eclipses.
Saros cycle 127 opened July 9, 1275, with a penumbral lunar eclipse. The series will end Tuesday, Sept. 2, 2555, with a penumbral lunar eclipse. The opening eclipse's occurrence near the penumbra's southern edge and the closing eclipse's location near the penumbra's northern edge reflect the shared northward movement of Saros cycle 127 eclipses away from the lunar descending node.
The Saturday, Aug. 4, 1906, total lunar eclipse numbered as 36th in the Saros cycle 127 lineup of 72 eclipses and as seventh in the cycle's 16-member total lunar eclipse set.
The August 1906 total lunar eclipse's predecessor was the total lunar eclipse of Monday, July 23, 1888. The July 1888 total lunar eclipse appeared as 35th in the Saros 127 cycle's 72-eclipse lineup and as sixth in the cycle's 16-member total lunar eclipse set.
The August 1906 total lunar eclipse's successor was the total lunar eclipse of Thursday, Aug. 14, 1924. The August 1924 total lunar eclipse occurred as 37th in the Saros 127 cycle's 72-eclipse lineup and as eighth in the cycle's 16-member total lunar eclipse set.
The total lunar eclipse of Tuesday, May 29, 1798, opened Saros 127 cycle's 16-member total lunar eclipse set. The May 1798 total lunar eclipse numbered as 30th in the Saros 127 cycle's 72-eclipse lineup.
A total lunar eclipse on Friday, Nov. 9, 2068, will close Saros 127 cycle's set of 18 total lunar eclipses. The November 2068 total lunar eclipse will number as 45th in the Saros 127 cycle's lineup of 72 lunar eclipses.
The NASA Eclipse Web Site's extreme durations predicted by American astronomer Fred Espenak (born 1953) and Belgian mathematical astronomer Jean Meeus (born Dec. 12, 1928) reveal the August 1906 total lunar eclipse's predecessor, the Monday, July 23, 1888, total lunar eclipse, as Saros 127 cycle's longest total lunar eclipse. The July 1888 total lunar eclipse had a duration of 1 hour 41 minutes 46 seconds.
Credit as Saros 127 cycle's shortest total lunar eclipse goes to the 16-member total lunar eclipse set's closer, the total lunar eclipse of Friday, Nov. 9, 2068. The set's closing eclipse will have a duration of 18 minutes 21 seconds.
The takeaways for the Saturday, Aug. 4, 1906, total lunar eclipse belonging to Saros cycle 127 are that the event occurred as 36th in the Saros cycle 127 lineup of 72 eclipses and as seventh in the cycle's 16-member set of total lunar eclipses; that the August 1906 total lunar eclipse's predecessor, the Monday, July 23, 1888, total lunar eclipse, qualifies as Saros 127 cycle's longest total lunar eclipse; that the cycle's last total lunar eclipse, the Friday, Nov. 9, 2068 total lunar eclipse, will close the 16-member total lunar eclipse set as Saros 127 cycle's shortest total lunar eclipse.
