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 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 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.

[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.

When a solar eclipse crosses the U.S. in mid-August at descending node (even numbered saros), the path tracks a large distance southward.

Their appearance and longitude are irregular due to a lack of synchronization with the anomalistic month (period of perigee).
