A total solar eclipse will occur at the Moon's descending node of orbit on Saturday, August 12, 2045,^[1] with a magnitude of 1.0774. 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. Occurring about 7 minutes after perigee (on August 12, 2045, at 17:35 UTC), the Moon's apparent diameter will be near its maximum.^[2]

It will be the fourth longest eclipse of the 21st century with a magnitude of 1.0774. 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, Texas, Arkansas, northeastern Louisiana, Mississippi, Alabama, Georgia and Florida. The total eclipse will be greatest over the Bahamas, before continuing over the Turks and Caicos Islands, the Dominican Republic, Haiti, northeastern Venezuela, Trinidad and Tobago, Guyana, Suriname, French Guiana, and northeastern Brazil. A partial solar eclipse will also be visible for parts of the Russian Far East, Hawaii, North America, Central America, the Caribbean, northern and central South America, and West Africa.

The path of totality of this eclipse will be seen over many major cities, including Reno, Salt Lake City, Colorado Springs, Oklahoma City, Tulsa, Jackson, Montgomery, Tallahassee, Tampa, Orlando, Fort Lauderdale, Miami, Nassau, Santo Domingo, Porlamar, Port of Spain, Georgetown, Paramaribo, Belém, São Luís, Joāo Pessoa and Recife.^[3] It will also be the second total eclipse visible from Little Rock in 21.3 years.^[3] 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 / 25.909900°N 78.53650°W / 25.909900; -78.53650, which is over the Atlantic Ocean east of Fort Lauderdale and south of Freeport, Bahamas.^[3]

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. This is because when a solar eclipse crosses the U.S. in mid-August at an ascending node (i.e. moves from south to north during odd-numbered saros), the path of the eclipse tracks from coast to coast. When a solar eclipse crosses the U.S. in mid-August at descending node (even numbered saros), the path tracks a large distance southward.^[4]

Eclipse season

This eclipse is part of an eclipse season, a period, roughly every six months, when eclipses occur. Only two (or occasionally three) eclipse seasons occur each year, and each season lasts about 35 days and repeats just short of six months (173 days) later; thus two full eclipse seasons always occur each year. Either two or three eclipses happen each eclipse season. In the sequence below, each eclipse is separated by a fortnight.

Saros 136

This eclipse is a part of Saros series 136, repeating every 18 years, 11 days, and containing 71 events. The series started with a partial solar eclipse on June 14, 1360. It contains annular eclipses from September 8, 1504 through November 12, 1594; hybrid eclipses 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. Its eclipses are tabulated in three columns; every third eclipse in the same column is one exeligmos apart, so they all cast shadows over approximately the same parts of the Earth.

The longest duration of annularity was produced by member 9 at 32 seconds on September 8, 1504, and the longest duration of totality was produced by member 34 at 7 minutes, 7.74 seconds on June 20, 1955. All eclipses in this series occur at the Moon’s descending node of orbit.^[7]

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.

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.

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.
