J’ai \u00e9t\u00e9 surpris par ces aurores, de part
\n– leur aspect sans structure
\n– leur intensit\u00e9
\n– leur sporadicit\u00e9
\n– leur d\u00e9ploiement grandiose dans le ciel<\/p>\n

et j’ai rat\u00e9 une grande partie du ph\u00e9nom\u00e8ne:
\n– arriv\u00e9e tardive sur un lieu d’observation
\n– capteur satur\u00e9 par l’intensit\u00e9.
\n– objectif grand angle classique alors que g\u00e9n\u00e9ralement je prends un fisheye
\n– first light avec une nouvelle optique, non test\u00e9e avant.<\/p>\n

Cette observation m’a cependant permis de me rappeler qu’il faut un minimum de pr\u00e9paration.
\nEt m’a permis une first light sur un objectif 21mm ouvert \u00e0 f1.4.<\/p>\n

Le ph\u00e9nom\u00e8ne s’est termin\u00e9 par une aurore plus classique avec des structures, en rouge ici.<\/p>\n
