Solar eclipse of August 12, 2045

A total solar eclipse will occur on Saturday, August 12, 2045, 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.

It will be the fourth longest eclipse of the 21st century with a magnitude of 1.0774 occurring just one hour after perigee.[1] It will be visible throughout much of the continental United States, with a path of totality running through northern California, Nevada, Utah, Colorado, Kansas, Oklahoma, Arkansas, Mississippi, Alabama, and Florida. The total eclipse will be greatest over the Bahamas, before continuing over the Turks and Caicos Islands, Cuba, Dominican Republic, Haiti, Venezuela, Trinidad and Tobago, Guyana, Suriname, French Guiana, and Brazil.

The path of totality of this eclipse will be seen over many major cities, including Reno, Salt Lake City, Colorado Springs, Oklahoma City, Tulsa, Tampa, Orlando, Fort Lauderdale, Miami, Nassau, Santo Domingo, Belém, São Luís and Recife.[2] It will also be the second total eclipse visible from Little Rock in 21 years.[2] Totality will last for at least 6 minutes along the part of the path that starts at Camden, Alabama, crossing Florida and ending near the southernmost Bahama Islands. The longest duration of totality will be 6 minutes 5.5 seconds at 25°54.594′N 78°32.19′W, which is over the Atlantic Ocean east of Fort Lauderdale and south of Freeport, Bahamas.[2]

The solar eclipse of August 21, 2017 had a very similar path of totality over the U.S., about 250 miles (400 km) to the northeast, also crossing the Pacific coast and Atlantic coast of the country. The problem is the lunar node. When a solar eclipse crosses the USA in mid August at ascending node, occurs from coast to coast, the last time was in 2017. When a solar eclipse crosses the USA in mid August at descending node, occurs from large distance southward.

Solar eclipses of 2044–2047

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.[4]

Saros 136

Solar Saros 136, repeating every 18 years, 11 days, contains 71 events. The series started with partial solar eclipse on June 14, 1360, and reached a first annular eclipse on September 8, 1504. It was a hybrid event from November 22, 1612, through January 17, 1703, and total eclipses from January 27, 1721 through May 13, 2496. The series ends at member 71 as a partial eclipse on July 30, 2622, with the entire series lasting 1262 years. The longest eclipse occurred on June 20, 1955, with a maximum duration of totality at 7 minutes, 7.74 seconds. All eclipses in this series occurs at the Moon’s descending node.[5]

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.
