July 11, 1991 – Mexico City, Mexico:
The Mexico UFO Wave
UFO enthusiasts regard the “Mexico UFO Wave” that began during the July 11th, 1991, total solar eclipse as one of the largest mass sightings ever recorded because numerous independent witnesses, along with at least a dozen amateur videographers, claimed to have filmed the same unexplained object.

The eclipse was itself remarkable, with totality lasting more than six minutes in some locations. Because millions of people were already watching and filming the sky, any unusual aerial object had an unusually high chance of being recorded.
During the eclipse, witnesses reported a bright metallic object hovering high above Mexico
City. It was usually described as silver, disc-shaped, or oval. Some said it remained nearly motionless, while others reported slow drifting, rotation, or a sudden departure after several minutes. Several videos appeared to show the object separately from the Sun.
Mexican journalist and UFO investigator Jaime Maussan collected many of the recordings and argued that they showed the same craft from different locations. The case greatly increased his international prominence.
Sightings continued after the eclipse. During the following weeks and months, Mexican television stations and newspapers reported luminous spheres, discs, and unexplained lights. For this reason, researchers often describe the eclipse sighting as the beginning of the broader 1991 Mexico UFO Wave, rather than an isolated incident.
Skeptics have proposed several explanations. Some believe the object was Venus, which can become visible when the sky darkens during a total eclipse. Others suggest camera shake, overexposure, lens reflections, atmospheric distortion, or automatic exposure changes in early-1990s camcorders made a bright object appear to move or shimmer. No physical evidence beyond videos and eyewitness testimony has confirmed an extraordinary craft.
Supporters argue that the object was filmed from different locations with different cameras and that independent witnesses described a stationary metallic object. They believe the apparent similarities between recordings suggest that something genuinely unusual was present. However, many tapes are low quality and lack precise timing, location, and positional data, making reliable comparison difficult.
The July 11, 1991 incident remains one of the most famous UFO cases in Mexican history. It continues to appear in documentaries as a major alleged mass sighting, though whether it involved an unidentified craft, Venus, optical effects, or a combination of mistaken observations remains unresolved.
