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 109 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 0718 Jun 17. The series will end with a partial eclipse north of the Ecliptic on 2016 Aug 18. The total duration of Saros series 109 is 1298.17 years. In summary:
First Eclipse = 0718 Jun 17 15:17:25 UT
Last Eclipse = 2016 Aug 18 09:42:19 UT
Duration of Saros 109 = 1298.17 Years
During Saros series 109, Earth experiences 73 lunar eclipses as follows:
All Eclipses = 73 = 100.0%
Penumbral (N) = 17 = 23.3%
Partial (P) = 39 = 53.4%
Total (T) = 17 = 23.3%
Umbral Eclipses = 56 = 76.7%
Central = 9 = 12.3%
Non-Central = 8 = 11.0%
Sequence of eclipses in Saros series 109: 9N 20P 17T 19P 8N
The longest and shortest eclipses of Saros series 109 as well as other eclipse extrema are listed below.
Longest Total Lunar Eclipse: 1349 Jul 01 Duration = 01h40m25s
Shortest Total Lunar Eclipse: 1529 Oct 17 Duration = 00h10m31s
Longest Partial Lunar Eclipse: 1547 Oct 28 Duration = 03h04m51s
Shortest Partial Lunar Eclipse: 0880 Sep 22 Duration = 00h52m55s
Largest Partial Lunar Eclipse: 1547 Oct 28 Magnitude = 0.9698
Smallest Partial Lunar Eclipse: 0880 Sep 22 Magnitude = 0.0510
