This is an incomplete list of alleged sightings of unidentified flying objects or UFOs in Argentina.

May 1962



 * On 11 and 18 May 1962 a UFOs were seen at the Espora Air Base.


 * On 12 May 1962 three truckmen, Valentino Tomassini, Gauro Tomassini and Humberto Zenobi were travelling on Route 35 from Bahia Blanca to Jacinto Aráuz. At 4,10 they saw an object on the ground in a field next to the road at a distance of 100 metres. The object looked like a railroad car and was illuminated. As their truck came close to it, the object rose up and crossed the road at a height of four metres; its lights went out and from the lower part of it came a reddish flame. At last, the object divided into two parts, which flew off in different directions.


 * On 21 May 1962 in Bahía Blanca Miguel Tohmé, photographer from La Nueva Provincia, took two photos of a UFO "the size of a soccer ball". One of the images appeared on the front page of the newspaper the next day.


 * Between 21 and 23 May 1962 UFOs were seen at the Port Belgrano Naval Base.

16 July 1965

 * In Buenos Aires 2 bright disks remained stationary for 10 minutes and then flew away at high speed. Due to the large number of reports that were being received, the Seventh Air Brigade sent 3 Gloster Meteor from Morón Air Base to investigate, with negative results.

1 December 1965

 * This sighting is called The Adhara Observatory UFO Lunar Transit. It takes place on December 1, 1965 at 8:30 pm, at the private-owner Adhara Observatory in San Miguel, Buenos Aires province. Scientists received several calls concerning strange objects visible on the moon. The staff of the observatory photographed the moon in fixed intervals; after processing, some photos revealed disk shaped objects flying in front of the moon. Some experts think that the UFOs on the photos are probably a fault in the processing of the film.

27 October 1973

 * On October 30 truck driver Dionisio Llanca was admitted to the Municipal Hospital of Bahía Blanca. He claimed that on the night of October 27, he left his uncle's home in Bahia Blanca to travel to Río Gallegos when he stopped to change a tire and became paralyzed by an intense light. According to Llanca, he saw an object in the sky and beings he described as two men and a woman who subjected him to some form of medical testing. Llanca says he briefly awoke hours later approximately 9 kilometers away. The case was investigated by UFO researcher Fabio Zerpa and published on his book El Reino Subterráneo.
