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 138 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 1503 Oct 05. The series will end with a partial eclipse south of the Ecliptic on 2982 Mar 30. The total duration of Saros series 138 is 1478.47 years. In summary:
First Eclipse = 1503 Oct 05 15:14:58 UT
Last Eclipse = 2982 Mar 30 16:23:22 UT
Duration of Saros 138 = 1478.47 Years
During Saros series 138, Earth experiences 83 lunar eclipses as follows:
All Eclipses = 83 = 100.0%
Penumbral (N) = 43 = 51.8%
Partial (P) = 14 = 16.9%
Total (T) = 26 = 31.3%
Umbral Eclipses = 40 = 48.2%
Central = 7 = 8.4%
Non-Central = 19 = 22.9%
Sequence of eclipses in Saros series 138: 22N 8P 26T 6P 21N
The longest and shortest eclipses of Saros series 138 as well as other eclipse extrema are listed below.
Longest Total Lunar Eclipse: 2369 Mar 24 Duration = 01h45m59s
Shortest Total Lunar Eclipse: 2495 Jun 08 Duration = 00h17m52s
Longest Partial Lunar Eclipse: 2513 Jun 19 Duration = 03h20m52s
Shortest Partial Lunar Eclipse: 1900 Jun 13 Duration = 00h08m11s
Largest Partial Lunar Eclipse: 2026 Aug 28 Magnitude = 0.9348
Smallest Partial Lunar Eclipse: 1900 Jun 13 Magnitude = 0.0012
