Saros cycle The saros () is a period of exactly 223 synodic months, 18 years 11 days and 8 hours, that can be used to predict eclipses of the Sun and Moon. One saros period after an eclipse, the Sun, Earth, and Moon return to approximately the same relative g ...

, repeating every 18 years, 11 days, containing 69 eclipses, 52 of which will be umbral (all annular). The first, and so far only, eclipse in the series was on 1 July 2011 and the last will be on 14 July 3237. The next eclipse will be a partial eclipse on 11 July 2029. This series is the most recent series to begin. The longest eclipse will be 8 minutes 28 seconds on 3 May 2516. This solar saros is linked to Lunar Saros 149.

Umbral eclipses

Umbral eclipses (annular, total and hybrid) can be further classified as either: 1) Central (two limits), 2) Central (one limit) or 3) Non-Central (one limit). The statistical distribution of these classes in Saros series 156 appears in the following table.
