Metonic series

It is the third of five Metonic cycle eclipses, each being separated by 19 years: The Metonic cycle repeats nearly exactly every 19 years and represents a Saros cycle plus one lunar year. Because it occurs on the same calendar date, the earth's shadow will in nearly the same location relative to the background stars.
