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 122 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 1022 Aug 14. The series will end with a partial eclipse south of the Ecliptic on 2356 Nov 08. The total duration of Saros series 122 is 1334.23 years. In summary:
First Eclipse = 1022 Aug 14 14:25:58 UT
Last Eclipse = 2356 Nov 08 20:55:08 UT
Duration of Saros 122 = 1334.23 Years
During Saros series 122, Earth experiences 75 lunar eclipses as follows:
All Eclipses = 75 = 100.0%
Penumbral (N) = 32 = 42.7%
Partial (P) = 15 = 20.0%
Total (T) = 28 = 37.3%
Umbral Eclipses = 43 = 57.3%
Central = 6 = 8.0%
Non-Central = 22 = 29.3%

The longest and shortest eclipses of Saros series 122 as well as other eclipse extrema are listed below.
Longest Total Lunar Eclipse: 1707 Oct 11 Duration = 01h40m43s
Shortest Total Lunar Eclipse: 1563 Jul 05 Duration = 00h26m18s
Longest Partial Lunar Eclipse: 2068 May 17 Duration = 03h19m45s
Shortest Partial Lunar Eclipse: 1419 Apr 10 Duration = 00h46m36s
Largest Partial Lunar Eclipse: 2068 May 17 Magnitude = 0.9587
Smallest Partial Lunar Eclipse: 1419 Apr 10 Magnitude = 0.0462
