On June 15, 2015, a witness in Aveyron observed and filmed a bright light in the northwest sky. What caught their attention was a sphere that appeared to be placed in front of the star. Although no other witnesses were reported, the testimony was considered fairly solid due to the two videos captured. However, the investigation concluded that the most likely explanation was an optical defect. The out-of-focus image of Venus, captured with a strong zoom, created an illusion that made the witness believe there was a sphere in front of the star.
The case was classified as "A," indicating that it is not an unexplained phenomenon, but a conventional observation with a technical explanation. The report details how incorrect focusing and prolonged use of the zoom can create visual artifacts that deceive the eye and brain. Despite the uniqueness of the testimony, the quality of the recordings allowed investigators to rule out more exotic explanations and provide a reasonable explanation based on optical physics.
