Bonjour,
\nVoici deux photos des nuages noctulescents qui ont \u00e9t\u00e9 visibles ce vendredi 21 juin au soir. Les clich\u00e9s sont pris depuis un balcon \u00e0 Ch\u00ean\u00e9e en banlieue li\u00e9geoise avec un apn Canon 60D, objectif Tamron 10-24mm r\u00e9gl\u00e9 sur 22mm de focale, 400 ISO, F\/D 6.3.<\/p>\n

A 23hr30, 2 secondes de pose<\/p>\n

A 23hr59, 6 secondes de pose<\/p>\n

Ce type de nuage se trouve \u00e0 une centaine de kilom\u00e8tres d’altitude, bien au del\u00e0 des nuages habituels qui ne d\u00e9passent pas une douzaine de kilom\u00e8tres pour les cirrus. Ils sont visibles parce qu’\u00e9clair\u00e9s directement par le soleil qui ne descend pas tr\u00e8s bas sous l’horizon au environs du solstice d’\u00e9t\u00e9.
\nPour une explication plus compl\u00e8te, voir l’explication qu’en donne Pierre Ponsard avec qui j’en ai observ\u00e9 r\u00e9cemment \u00e0 La Fosse: https:\/\/www.youtube.com\/watch?v=2rPiW-eCbQ8<\/a><\/p>\n

Bon weekend,
\nJ-Luc<\/p>\n\n\n
