The two longest occurrence of this series were on September 20, 1736 and October 1, 1754 when totality lasted 106 minutes.[1]

It last occurred on February 10, 1971 and will next occur on March 3, 2007.

Metonic cycle (19 years)

This is the third of five Metonic lunar eclipses.

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.
