A total solar eclipse will occur on Wednesday, May 11, 2078. 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.

Solar eclipses 2076–2079

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]

Saros 139

It is a part of saros series 139, repeating every 18 years, 11 days, 8 hours, containing 71 events. The series started with partial solar eclipse on May 17, 1501. It contains hybrid eclipses on August 11, 1627 through to December 9, 1825 and total eclipses from December 21, 1843 through to March 26, 2601. The series ends at member 71 as a partial eclipse on July 3, 2763. Its eclipses are entabulated in three columns; each one in the same column, every third eclipse, is one exeligmos apart so cast shadows over approximately the same parts of the Earth.

The solar eclipse of June 13, 2132 will be the longest total solar eclipse since July 11, 1991 at 6 minutes, 55.02 seconds.

The longest duration of totality will be produced by member 39 at 7 minutes, 29.22 seconds on July 16, 2186.[2] After that date each duration will decrease, until the series end. This date is the longest solar eclipse computed between 4000 BC and 6000 AD.[3] Saros series eclipses are during the Moon’s ascending node (a term related to our equator and polar-naming conventions).

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 18th century:

Tritos series

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.
