Photographed in Pas-de-Calais, France

On November 10, 2014 at 10:00 PM, a witness looks out his window and sees a slightly blinking bright point in the sky. The UAP moves very slowly to the right, while changing color very rapidly. The witness tries to photograph the UAP, without success. The observation ends between 12:45 AM and 1:00 AM. As the witness begins filling out a GEIPAN Electronic Questionnaire (EQ) around 1:40 AM, he looks out the window again and sees the UAP again. He loses sight of it around 2:30 AM. Only one testimony will be collected. The length of the observation time (about 3 hours for the first phase and 45 minutes for the second) as well as the fact that the UAP moves very slowly to the right are entirely characteristic of a misidentification of an astronomical type. Moreover, the movement from West to North accompanied by a decrease in the UAP's angular height is entirely characteristic of the observation of a celestial body observed toward the Northwest. If this hypothesis is correct, the observation of the UAP would therefore involve two different stars, assimilated into a single object by the witness, the absence of observation during 45 minutes between 1:00 AM and 1:45 AM favoring this type of confusion. The UAP's rapid color changes (red, green, blue) are also entirely characteristic of the observation of a bright celestial body, whose light twinkles due to high-altitude winds. A reconstruction on Stellarium for November 10, 2014 at 10:00 PM shows that a remarkably bright celestial body, the star Vega (magnitude 0.0), is located at an azimuth perfectly consistent with that of the UAP (297° versus 298° estimated by the witness) (see the investigation report). Of average strangeness, but of sufficient consistency, this case turns out to be a certain misidentification with the stars Vega and Deneb, whose positions correspond exactly to that of the UAP at the indicated times. Additionally, the arrival of a rainy weather disturbance at the time of the observation caused high-altitude winds making the stars twinkle, corresponding to the UAP's rapid color changes. The small apparent movements perceived by the witness are the result of the autokinetic illusion. This case is classified as A, misidentification with the stars Vega and Deneb.
