Project 10073 Record Card — Uruguay, October 1958

This document is a collection of records from the Uruguayan Centro de Investigacion de Objetos Voladores Inidentificados (CIOVI) regarding a sighting on October 15, 1958, in Sta. Lucia, Canelones. The primary witness, a 32-year-old judicial official, reported observing a luminous object at approximately 20:00 hours. The witness described the object as having an oval, metallic appearance, roughly the size of an orange at distance. It exhibited an oscillating movement, including ascents and descents, and was surrounded by red, blue, and green lights that moved rhythmically around a central yellowish-white light. The witness also noted a horizontal, smoke-like trail extending from one end of the object. The object moved in a straight line before changing directions and eventually disappearing. The witness explicitly stated that the object made no sound and that she did not experience any physical or electromagnetic effects. The CIOVI evaluation, dated October 13, 1958 (noting the discrepancy in dates between the report and the evaluation), considers the witness account complete and reliable. The investigators concluded that the sighting was undoubtedly a 'flying saucer' (disco volador), noting that the characteristics—specifically the shape, movement, and colored lights—were consistent with other cases in their files. They specifically highlighted the horizontal smoke-like trail as a unique feature for which they had no previous record. The document also includes a secondary, less detailed report of a similar sighting, and a list of coordinates and times, possibly related to other observations or tracking data. The overall tone of the document is one of serious investigation, with the CIOVI acting as a formal body under the auspices of the Uruguayan Air Force Intelligence Service.
