NANCY (54) 03.02.2012

A report dated 14 January 2015 concerned a sighting in Nancy (54) on 3 February 2012 at 18:04. A witness saw a bright yellow oblong form moving slowly and silently in a straight line to the north/northwest. It disappeared after a few minutes; the observation duration is specified as 2 minutes, during which he took photographs. No other account was collected. GEIPAN finds the appearance consistent with the condensation trail of a distant aircraft, more than 50 km away, illuminated by sunset. The Sun had set about 30 minutes earlier. Under clear skies, such effects can be seen in the half-hour after sunset or before sunrise. The source refers to “Des traînées d'avions étranges,” on page 3 of the news section at www.cnes-geipan.fr. GEIPAN classifies the case B: probable aircraft contrail.
