Solar eclipses are grouped by their saros number, each series lasts between 1200 and 1600 years and contains from 69 to 87 solar eclipses (most often 70 to 73). Solar eclipses in odd series exist at the ascending node of the Moon's orbit, and even series occur at the descending nodes.
Each series begins with partial eclipses, transitions into umbral eclipses (which includes annular, hybrid, and total eclipses), and then reverses back to partial. The counts for each type and their order are listed below. Ongoing saros series are highlighted according to the type of eclipses currently being produced.
Series have been indexed as -13 to 190 (active between roughly 2000 BCE and 3000 CE), with events summarized:
