Officials at the Chilean government agency in charge of investigating anomalous aerial phenomena have confirmed that photos taken last year at a copper mine in the remote north Andes are definitely photos of an anomalous aerial phenomenon, or Objecto Volante Non Identificado.
The photos show a disc-shaped unidentified flying object with an internal glow, according to the experts, who concluded that the photos were genuine.
This is how the official report starts out, as translated by the UFO Chronicles:
The Collahuasi Case
By Comité de Fenómenos Aéreos Anómalos
(Translation By Scott Corrales)
In Mid-2013, several witnesses observed an unusual phenomenon for a couple of hours from their place of work – the Collahuasi Mining Company – at an elevation of 4300 meters.
They took several photographs and did not wish to delve further into the matter. Over time, two photographs were delivered to the group leader and he forwarded them to CEFAA, ascertaining that the participants were professionals in the fields of electricity, electronics and fluid control, all of them endowed with highly pragmatic mindsets.
They described the phenomenon as a brilliant, flattened disk with an approximate diameter of between 5 to 10 meters. It made rising, descending and horizontal motions in short segments some 600 meters over the surface. At times it could be clearly seen as a disk, later adopting the shape of a shining balloon, although the most evident shape was that of a silvery, fixed and static disk. The witnesses were left with the impression that the movements were associated to a given control.
Weather conditions were outstanding. Evidence was analyzed by a meteorologist, who discarded the possibility of lenticular cloud formation.
An expert in image analysis (whose full study is provided in this site) concluded that the photographs correspond to an object that has not been identified.
