PARIS (75) 23.08.2015

On the night of August 23-24, 2015, witnesses were intrigued by the presence in the Parisian sky of an intense red glow. They independently reported their observation. The first witness began his observation on 23 August 2015 from 23:25: he observed a very bright red glow in the Parisian sky towards the South-East. This light seemed permanent (with a change of intensity) and moved slightly into the sky before returning to its initial position. Very intrigued, the witness took photographs with his smartphone and observed the phenomenon until 01:00 in the morning before going to bed (see the investigation report). A second witness on August 24, 2015 at 00:58 a.m. observed a fiery-red ball in the northwest above the Parisian buildings for 10 minutes. The witness had time to take three photographs with a mobile phone. He went to wake his wife, but the object had disappeared by the time he returned to the window (see the investigation report). The accounts have good evidential support, with sufficient data provided by the witnesses and usable. Several UAP photographs were made and could be used for analysis leading to useful cross-checks. In conclusion, the physical and dynamic characteristics of the UAP observed and photographed by the witnesses resemble those of a powerful red laser used by an individual in Paris, from a building rooftop, whose luminous spot produced by its impact on the low cloud or mist layer is similar to the UAP. The ambient light conditions surrounding the witnesses during their observation and photography prevent the laser beam from being visible, both with the naked eye and with the photographic sensor, except after enhancement of one photograph. The strangeness of this case is finally quite low and is mainly caused by the luminous intensity of the UAP and its persistence for more than 1 hour 30 minutes. Both testimonies are independently analyzed through consistent photographs and testimonies (see investigation reports). GEIPAN classifies the case B as a probable observation of the light spot on the cloud or mist layer of a powerful red laser, projected from the top of one of the buildings of the 11th arrondissement of Paris.
