The periodicity and recurrance of solar (and lunar) eclipses is governed by the Saros cycle, a period of approximately 6,585.3 days (18 years 11 days 8 hours). When two eclipses are separated by a period of one Saros, they share a very similar geometry. The eclipses occur at the same node with the Moon at nearly the same distance from Earth and at the same time of year. Thus, the Saros is useful for organizing eclipses into families or series. Each series typically lasts 12 to 13 centuries and contains 70 or more eclipses.
Lunar eclipses of Saros series 123 all occur at the Moon’s descending node and the Moon moves northward with each eclipse. The series began with a partial eclipse south of the Ecliptic on 1087 Aug 16. The series will end with a partial eclipse north of the Ecliptic on 2385 Oct 19. The total duration of Saros series 123 is 1298.17 years. In summary:
First Eclipse = 1087 Aug 16 21:05:57 UT
Last Eclipse = 2385 Oct 19 05:25:24 UT
Duration of Saros 123 = 1298.17 Years
During Saros series 123, Earth experiences 73 lunar eclipses as follows:
All Eclipses = 73 = 100.0%
Penumbral (N) = 34 = 46.6%
Partial (P) = 14 = 19.2%
Total (T) = 25 = 34.2%
Umbral Eclipses = 39 = 53.4%
Central = 9 = 12.3%
Non-Central = 16 = 21.9%
Sequence of eclipses in Saros series 123: 24N 6P 25T 8P 10N
The longest and shortest eclipses of Saros series 123 as well as other eclipse extrema are listed below.
Longest Total Lunar Eclipse: 1736 Sep 20 Duration = 01h46m34s
Shortest Total Lunar Eclipse: 1628 Jul 16 Duration = 00h23m21s
Longest Partial Lunar Eclipse: 2079 Apr 16 Duration = 03h24m07s
Shortest Partial Lunar Eclipse: 2205 Jul 02 Duration = 01h00m40s
Largest Partial Lunar Eclipse: 2079 Apr 16 Magnitude = 0.9503
Smallest Partial Lunar Eclipse: 2205 Jul 02 Magnitude = 0.0658
