A total solar eclipse will occur on Friday, May 20, 2050. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. This eclipse is a hybrid eclipse, starting and ending as an annular solar eclipse.

Related eclipses[edit]

Solar eclipses 2047–2050[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 lunar eclipses on January 26, 2047 and July 22, 2047 occur on the previous lunar year eclipse set.

Saros 148[edit]

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[edit]

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 1818 Oct 29

• Solar Saros 141: Annular Solar Eclipse of 1847 Oct 09

• Solar Saros 142: Total Solar Eclipse of 1876 Sep 17

In the 22nd century:

Solar Saros 150: Partial Solar Eclipse of 2108 Apr 11

Solar Saros 151: Annular Solar Eclipse of 2137 Mar 21

Solar Saros 152: Total Solar Eclipse of 2166 Mar 02

Solar Saros 153: Annular Solar Eclipse of 2195 Feb 10

Metonic series[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). All eclipses in this table occur at the Moon's descending node.[3]
