An object was observed. Gravity effects were noted. One luminous object was observed by one female witness, an experienced observor, at a factory (Grosso; Quiroga). One 8.3-foot-tall pallid being, wearing a luminous blue-green suit, was seen.

23:13: Enrique Moreno was delivering documents in the Ika-Renault factory when the fluorescent lights in the engineering room went on and off three times. There was an accompanying noise like that of a turbine lasting for several seconds. Then, driving his motor runabout outside the plant, he briefly glimpsed "a sort of rainbow very near the ground," and thought no further of it until he suddenly encountered a tall figure, glowing a bluish green, moving among some piles of chassis beside his route. As he approached within 30 yards, the figure swung around, in a stiff, mechanical way, to face him, and at the same time his engine faltered, and quit when he came opposite the being. This humanoid figure, strongly built and about 7.5 ft tall had eyes like yellow light bulbs, ears that rose above the skull in a point, a square chin, and a slit-like mouth. The face appeared pale green, but this may have been a reflection of the clothing, a one-piece tight fitting coverall of luminescent bluish-green, with a broad silvery belt. Moreno felt an intolerable hum in his ears and a sensation of heat and itching over his whole body; there was a smell of burning oil. His arms and legs were paralyzed. After 30 seconds of confrontation, his motorcycle shot off to the left on its own volition at high speed, and the witness returned to the Security Office without his conscious control. He arrived at 2330, but his wristwatch had stopped at 2313A, leaving 15 minutes unaccounted for. Moreno was in a highly agitated state, and subsequently suffered nausea and pains in the neck, as well as a burning sensation in his eyes. At the encounter site later, two rectangular "footprints" 8 x 16 were found and the soil there was hot.

23:30 Independent witnesses, one a lady named Quiroga, saw near a local auto plant a luminous object which by means of a solid beam of blue light picked up a tall humanoid entity. It apparently took the being up through the tube of light and into the object. Others saw a luminous object rising up to the sky from the vicinity of the auto plant.
