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 131 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 1427 May 10. The series will end with a partial eclipse north of the Ecliptic on 2707 Jul 07. The total duration of Saros series 131 is 1280.14 years. In summary:
First Eclipse = 1427 May 10 23:32:43 UT
Last Eclipse = 2707 Jul 07 06:35:41 UT
Duration of Saros 131 = 1280.14 Years
During Saros series 131, Earth experiences 72 lunar eclipses as follows:
All Eclipses = 72 = 100.0%
Penumbral (N) = 15 = 20.8%
Partial (P) = 42 = 58.3%
Total (T) = 15 = 20.8%
Umbral Eclipses = 57 = 79.2%
Central = 7 = 9.7%
Non-Central = 8 = 11.1%
Sequence of eclipses in Saros series 131: 7N 22P 15T 20P 8N
The longest and shortest eclipses of Saros series 131 as well as other eclipse extrema are listed below.
Longest Total Lunar Eclipse: 2094 Jun 28 Duration = 01h41m16s
Shortest Total Lunar Eclipse: 2202 Sep 03 Duration = 00h22m56s
Longest Partial Lunar Eclipse: 2220 Sep 13 Duration = 03h08m46s
Shortest Partial Lunar Eclipse: 1553 Jul 25 Duration = 00h18m16s
Largest Partial Lunar Eclipse: 1932 Mar 22 Magnitude = 0.9722
Smallest Partial Lunar Eclipse: 1553 Jul 25 Magnitude = 0.0069
