Spherical UFO sighted at EVA-4 in 1991

Summary

On the early morning of September 13, 1991, a security officer at EVA-4 in Roses (Girona) observed a luminous spherical object with a radius of about five meters. The phenomenon was seen at an approximate height of 150 meters, making circular movements with a radius of around 200 meters, without emitting any sound. The witness observed it for five to six minutes and asked other guards if they had noticed anything unusual, but there were no other reports or anomalies.

The official report, preserved at the Central Library of the Spanish Air Force, states that two other guards also confirmed the sighting. Despite the unusual nature of the event, the documents do not indicate any risks or need for classification, and the file was declassified in 1996. This case is part of the Air Force's UFO records, which include testimonies of unexplained events occurring at military installations.
