Codes naming an eclipse's type, date and magnitude.
Also known as: Saros number, Eclipse type code
Eclipses are catalogued by type — total, annular, partial or hybrid — with a magnitude and a saros number identifying the repeating family they belong to. The saros cycle repeats a similar eclipse about every eighteen years, shifted a third of the way round the world each time.
