A total solar eclipse occurred at the Moon's descending node of orbit on Thursday, July 11, 1991,[1] with a magnitude of 1.08.

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 8 hours after perigee (on July 11, 1991, at 11:00 UTC), the Moon's apparent diameter was larger.

Totality began over the Pacific Ocean and Hawaii, moving across Mexico, down through the Central American countries of Guatemala, El Salvador, Honduras, Nicaragua, Costa Rica and Panama, across Colombia and ending over Brazil.

[3] A team of 320 people from NASA's Johnson Space Center made observation in Mazatlán, Mexico.

In the end, a hole in the clouds appeared in El Cid in western Mazatlan, through which the corona and prominences was visible.

[4] Scientists from the Royal Observatory of Belgium, the Institute of Geodesy and Geophysics of the Chinese Academy of Sciences, and the Institute of Geophysics of the National Autonomous University of Mexico made observations in Mexico City to study the change in gravity during a total solar eclipse.

[7] Reviewers disputed the claim in 2014, concluding that, "loose hieroglyphic readings and accommodating pattern matching occurs throughout the book.

"[8] The 1991 eclipse appears in the music video for Cosas del Amor, a duet by Vikki Carr and Ana Gabriel.

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