An account in Val-de-Marne, France

On July 15, 2009, from 0:26 to 0:28, a witness observes and photographs, from a balcony on the 4th floor, a very bright luminous phenomenon in the cloudy sky. No other testimony will be collected on this phenomenon. The investigator will note an inconsistency in the testimony about the time of the event: the witness writes "from 0:26 to 0:28 as noted and as indicated on the photos," while the photos mention 23:28: the observation would therefore have taken place on July 14, 2009. If the time of the photo is 23:28, it is exactly the time of the big fireworks display launched from the Eiffel Tower on the occasion of its 120th anniversary. The 2-minute duration of the observation may correspond to the grand finale (see the link given in the investigation report). If it really is 0:26, one might think of another light show, but undetermined. This case is classified B: probable observation of the reflection on the clouds of the light shows of July 14, 2009. The uncertainty about the time of the observation does not allow confirming whether it was the fireworks or another light show.
