COUERON (44) 07.10.2011

On 7 October 2011 at about 22:15, a witness in Couëron (44) saw 3 pale-white luminous triangular objects themselves arranged in a triangle, moving northeast to southwest. A fourth object, separate and farther west, traveled at the same speed in the same direction. They moved silently below clouds and eventually disappeared into them. The sighting lasted 15 seconds. No other account was collected. GEIPAN considered sky lanterns because the 4 lights moved slowly in straight lines. However, their triangular shapes and motion perpendicular to the wind, based on Météociel records for Nantes and Saint-Nazaire, prevented confirmation; the witness also did not recognize lanterns. Aircraft fit poorly because of the lights' triangular shape and silence. GEIPAN classifies the case C: unidentified for lack of data.
