Le nuage que vous pouvez voir sur la photo a \u00e9t\u00e9 observ\u00e9 ce mercredi 02 juillet vers quatre heures du matin depuis l’observatoire de La Fosse. Il s’agit d’un nuage noctiluque et non de cirrus ordinaire. Ce type de nuages se forme vers 80 \u00e0 100 km d’altitude et ils ne sont visibles dans nos r\u00e9gions qu’aux alentours du solstice d’\u00e9t\u00e9, lorsque le Soleil ne descend pas \u00e0 plus de 15 degr\u00e9s sous l’horizon. Ce qui m’\u00e9tonne, c’est la hauteur \u00e0 laquelle il apparait au dessus de l’horizon. Ceci conforte la th\u00e8se selon laquelle les nuages noctiluques qui n’\u00e9taient \u00e0 l’origine visibles que dans les r\u00e9gions polaires se d\u00e9veloppent de plus en plus chaque ann\u00e9e et descendent de plus en plus vers des latitudes plus m\u00e9ridionales.
\n(Photo faite \u00e0 4hr02 locale avec le Canon 350D, focale de 18mm, ouverture 3,5 et temps de pose de 8 secondes; J’ai pos\u00e9 l’appareil sur un piquet de cloture pour \u00e9viter le flou de bouger). <\/p>\n\n\n
