Solar eclipses 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 148

Solar saros 148, repeating every about 18 years and 11 days, contains 75 events. The series started with a partial solar eclipse on September 21, 1653. It has annular eclipses on April 29, 2014, and May 9, 2032, and a hybrid eclipse on May 20, 2050. It has total eclipses from May 31, 2068, to August 3, 2771. The series ends at member 75 as a partial eclipse on December 12, 2987. The longest total eclipse will be on April 26, 2609, at 5 minutes and 23 seconds.^[2]

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 140: total solar eclipse of October 29, 1818
• Solar saros 141: annular solar eclipse of October 9, 1847
• Solar saros 142: total solar eclipse of September 17, 1876

Inex series members between 1901 and 2100:
August 30, 1905 (Saros 143)	August 10, 1934 (Saros 144)	July 20, 1963 (Saros 145)
June 30, 1992 (Saros 146)	June 10, 2021 (Saros 147)	May 20, 2050 (Saros 148)
May 1, 2079 (Saros 149)

In the 22nd century:

• Solar saros 150: partial solar eclipse of April 11, 2108
• Solar saros 151: annular solar eclipse of March 21, 2137
• Solar saros 152: total solar eclipse of March 2, 2166
• Solar saros 153: annular solar eclipse of February 10, 2195

Metonic series

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 descending node.^[3]
