UFO sighted in Uruguay in 1958

Summary

In October 1958, a Uruguayan citizen reported seeing a luminous and translucent object in the sky. The witness described it as a bright, pale white body with uniform movement and no signs of acceleration or deceleration. Although binoculars were used to observe it, its exact nature could not be identified. The official conclusion pointed to a weather balloon, although an astronomical phenomenon was also considered. The lack of conclusive evidence left the case unresolved.

The report from the Center for Investigation of Unidentified Flying Objects (CIOVNI) in Uruguay recorded this observation as insufficient for a definitive evaluation. The witness could not determine if the object had a metallic shape or performed rotational movements. Additionally, no electrical effects or environmental changes were recorded. Despite the clear description of the object's trajectory from north to south, there were no other witnesses or photographic evidence. The case remains one of many in UFO history that failed to achieve a clear explanation.
