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 117 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 1094 Apr 03. The series will end with a partial eclipse north of the Ecliptic on 2374 May 26. The total duration of Saros series 117 is 1280.14 years. In summary:
First Eclipse = 1094 Apr 03 17:26:38 UT
Last Eclipse = 2374 May 26 19:33:35 UT
Duration of Saros 117 = 1280.14 Years
During Saros series 117, Earth experiences 72 lunar eclipses as follows:
All Eclipses = 72 = 100.0%
Penumbral (N) = 32 = 44.4%
Partial (P) = 15 = 20.8%
Total (T) = 25 = 34.7%
Umbral Eclipses = 40 = 55.6%
Central = 13 = 18.1%
Non-Central = 12 = 16.7%
Sequence of eclipses in Saros series 117: 8N 8P 25T 7P 24N
The longest and shortest eclipses of Saros series 117 as well as other eclipse extrema are listed below.
Longest Total Lunar Eclipse: 1707 Apr 17 Duration = 01h46m18s
Shortest Total Lunar Eclipse: 1382 Sep 23 Duration = 00h10m02s
Longest Partial Lunar Eclipse: 1364 Sep 11 Duration = 03h24m28s
Shortest Partial Lunar Eclipse: 1238 Jun 29 Duration = 00h54m33s
Largest Partial Lunar Eclipse: 1364 Sep 11 Magnitude = 0.9212
Smallest Partial Lunar Eclipse: 1238 Jun 29 Magnitude = 0.0511
