An object was observed. Occupants of the craft were seen. One object was observed (Gorche De Veron).

While Mrs Mabel Gorchs de Veron was crossing the central Plaza Colon, she observed a bright green light that made her look up. There, 100 meters above her, was a circular object about 10 meters in diameter, emitting a bluish luminosity, with a cupola on its upper part and a row of little windows around it, through which a dim light came from the inside, where there could be seen "some strange figures, looking out." The craft remained motionless for several seconds, until a commercial plane went by; the UFO followed it for a few moments before going away toward the sea. It seems that this phenomenon was also observed by a newspaperman of the local daily and by a group of office employees of the Argentine National Airlines. Later, at 1915 Mr. Villegas succeeded in seeing it with his Urano 100 telescope of 200x magnification, making out some shadows that seemed to be moving around inside it; the object was already at a greater altitude. The UFO remained in the sky of Mar Del Plata for 4 hours, during which it was seen by hundreds of witnesses.
