A total solar eclipse occurred on November 12, 1966.
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.

The path of totality cut a swath across South America from north of Lima, Peru, passing the northeastern tip of Chile, Bolivia, 
Northwest of Argentina, southwestern tip of Ñeembucú Department in Paraguay, nearly to the southernmost tip of Brazil.
