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 120 all occur at the Moon’s ascending node and the Moon moves southward with each eclipse. The series began with a partial eclipse north of the Ecliptic on 0982 Oct 05. The series will end with a partial eclipse south of the Ecliptic on 2479 Apr 07. The total duration of Saros series 120 is 1496.50 years. In summary:
First Eclipse = 0982 Oct 05 16:56:11 UT
Last Eclipse = 2479 Apr 07 00:20:17 UT
Duration of Saros 120 = 1496.50 Years
During Saros series 120, Earth experiences 84 lunar eclipses as follows:
All Eclipses = 84 = 100.0%
Penumbral (N) = 45 = 53.6%
Partial (P) = 14 = 16.7%
Total (T) = 25 = 29.8%
Umbral Eclipses = 39 = 46.4%
Central = 5 = 6.0%
Non-Central = 20 = 23.8%
Sequence of eclipses in Saros series 120: 22N 7P 25T 7P 23N
The longest and shortest eclipses of Saros series 120 as well as other eclipse extrema are listed below.
Longest Total Lunar Eclipse: 1776 Feb 04 Duration = 01h45m29s
Shortest Total Lunar Eclipse: 1505 Aug 14 Duration = 00h46m20s
Longest Partial Lunar Eclipse: 1487 Aug 04 Duration = 03h26m35s
Shortest Partial Lunar Eclipse: 1379 May 31 Duration = 01h01m49s
Largest Partial Lunar Eclipse: 1956 May 24 Magnitude = 0.9698
Smallest Partial Lunar Eclipse: 1379 May 31 Magnitude = 0.0658
