Comments :
07h05-08h00 : Météo : vent plus soutenu qu'hier ayant favorisé la perception de la migration et l'ayant possiblement "dopée". 15 à 20 km E à ESE. Diminue cependant dès 9h15 alors que la couverture nuageuse initialement très faible devient forte. 8°C en début de séance ; 17°C en fin de séance. Observateur : Thierry Rigaux
