Derni\u00e8re soir\u00e9e sous les aurores.
\nAvant de partir vers la Scandinavie, les pr\u00e9visions \u00e0 long terme donnaient un indice d’aurores (Kp Index) assez bon pour la fin du s\u00e9jour.

\nVoici sur quelques heures…<\/p>\n

\nLe premier d\u00e9veloppement commence apr\u00e8s le coucher de soleil.
\nQuelques images de ce d\u00e9veloppement.

L’animation est ici sur youtube.<\/a><\/p>\n

===
\nL’intensit\u00e9 sature le capteur.
\nVoici la fin du d\u00e9veloppement en r\u00e9duisant le temps de pose.

\nJ’aime assez bien l\u2019animation qui suit, m\u00eame si ce n’est pas la plus spectaculaire. Toutes les images post\u00e9es ici ont \u00e9t\u00e9 captur\u00e9es avec un Fisheye; ce qui donne la dimension du ph\u00e9nom\u00e8ne.
\n\"\"<\/a><\/p>\n

L’animation est ici.<\/a><\/p>\n

===
\nEncore un d\u00e9veloppement qui remplit tout le champ et sature le capteur.

L’animation.<\/a><\/p>\n

\nLe r\u00eave en aurore bor\u00e9ale est de voir une \u00ab\u00a0cath\u00e9drale\u00a0\u00bb.
\nCette s\u00e9quence y tend un peu, mais n’a pas la puissance tant esp\u00e9r\u00e9e.

\nEncore un d\u00e9veloppement.
