An account in Vaucluse, France

On July 17, 2014 at around 12:15 AM, a witness saw in the sky a yellow-orange luminous point close to the color of stars, with a very unusual trajectory (straight line, descent, half-turn, rising zig-zag) before disappearing very quickly. No other testimony was collected. Given the objective elements described in the investigation report, namely the observation time and duration, the starting and ending azimuth of the observation, the good visibility of the ISIS satellite and the exceptional apparent magnitude of the satellite, as well as the "micro-nystagmus" effect (autokinetic illusion), we can conclude that the case involves the probable observation of the star Arcturus, then of the ISIS 1 satellite. However, one important point of the observation does not match this hypothesis; it could be a confusion or a false memory, but we have no conclusive evidence to adopt this hypothesis. This case is to be classified as "C" for lack of cross-checking that would confirm the "ISIS" hypothesis, or confirm the complex movement of the observed luminous point.
