Notre \u00e9toile est toujours bien active malgr\u00e9 que nous venons de passer le maximum d’activit\u00e9 dans son cycle de 11 ans.

Lunt de 60mm et cam\u00e9ra zwo asi 1600 mc pro.
\nVid\u00e9o de 35s \u00e0 la vitesse de 15 images\/s. J’ai pris les 30% des meilleures images de la vid\u00e9o que j’ai ensuite assembl\u00e9 pour ne faire qu’une seule image. J’ai alors invers\u00e9 les couleurs pour que la r\u00e9gion active apparaisse sombre (elle est normalement bien brillante et blanche) et pour mettre en \u00e9vidence les structures tortueuses dues au champ magn\u00e9tique.<\/p>\n\n\n
