Partial solar eclipses on June 23, 2047 and December 16, 2047 occur on the next lunar year eclipse set.

Solar saros 141, repeating every about 18 years, 11 days, and 8 hours, contains 70 events. The series started with partial solar eclipse on May 19, 1613. It contains 41 annular eclipses from August 4, 1739, to October 14, 2460. There are no total eclipses in this series. The series ends at member 70 as a partial eclipse on June 13, 2857. The longest annular eclipse occurred on December 14, 1955, with maximum duration of annularity at 12 minutes and 9 seconds. All eclipses in this series occur at the Moon’s ascending node.[2]

This eclipse is a part of the long period inex cycle, repeating at alternating nodes, every 358 synodic months (≈ 10,571.95 days, or 29 years minus 20 days). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee). However, groupings of 3 inex cycles (≈ 87 years minus 2 months) comes close (≈ 1,151.02 anomalistic months), so eclipses are similar in these groupings.

Inex series members between 1901 and 2100:
May 18, 1901 (Saros 136)	April 28, 1930 (Saros 137)	April 8, 1959 (Saros 138)

January 16, 2075 (Saros 142)

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). All eclipses in this table occur at the Moon's ascending node.

This eclipse is a part of a tritos cycle, repeating at alternating nodes every 135 synodic months (≈ 3986.63 days, or 11 years minus 1 month). Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee), but groupings of 3 tritos cycles (≈ 33 years minus 3 months) come close (≈ 434.044 anomalistic months), so eclipses are similar in these groupings.
