Solar eclipses of 1971-1974[edit]

This eclipse is a member of a semester series. An eclipse in a semester series of solar eclipses repeats approximately every 177 days and 4 hours (a semester) at alternating nodes of the Moon's orbit.[1]

Note: Partial solar eclipses on February 25, 1971 and August 20, 1971 occur in the next lunar year set.

Metonic cycle[edit]

The metonic series repeats eclipses every 19 years (6939.69 days), lasting about 5 cycles. Eclipses occur in nearly the same calendar date. In addition, the octon subseries repeats 1/5 of that or every 3.8 years (1387.94 days).

Half-Saros cycle[edit]

A solar eclipse will be preceded and followed by lunar eclipses by 9 years and 5.5 days (a half saros).[2] This solar eclipse is related to two penumbral lunar eclipses of Lunar Saros 109 on the first and second columns.
