Solar eclipses of 2047–2050

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 lunar eclipses on January 26, 2047 and July 22, 2047 occur on the previous lunar year eclipse set.

Saros 128

This eclipse is a member of the Solar Saros cycle 128, which includes 73 eclipses occurring in intervals of 18 years and 11 days. The series started with partial solar eclipse on August 29, 984 AD. From May 16, 1417, through June 18, 1471, the series produced total solar eclipses, followed by hybrid solar eclipses from June 28, 1489, through July 31, 1543, and annular solar eclipses from August 11, 1561, through July 25, 2120. The series ends at member 73 as a partial eclipse on November 1, 2282. All eclipses in this series occurs at the Moon's descending node.

Inex series

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.

In the 19th century:

• Solar Saros 120: Total Solar Eclipse of 1816 Nov 19

• Solar Saros 121: Hybrid Solar Eclipse of 1845 Oct 30

• Solar Saros 122: Annular Solar Eclipse of 1874 Oct 10

In the 22nd century:

• Solar Saros 130: Total Solar Eclipse of 2106 May 03

• Solar Saros 131: Annular Solar Eclipse of 2135 Apr 13

• Solar Saros 132: Hybrid Solar Eclipse of 2164 Mar 23

• Solar Saros 133: Total Solar Eclipse of 2193 Mar 03

Metonic cycle

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).
