Capture du vendredi 7 novembre; la r\u00e9gion (tr\u00e8s) active 4274 sur notre \u00e9toile est le si\u00e8ge d’\u00e9ruptions importantes (flares). La raison est que les p\u00f4les magn\u00e9tiques de cette tache solaire ne sont pas dispos\u00e9s comme d’habitude. La cons\u00e9quence est le d\u00e9veloppement d’\u00e9ruptions plus fortes. Celles-ci ont provoqu\u00e9 l’apparition d’aurores polaires (visibles la nuit derni\u00e8re aux Etats-Unis et Canada) ainsi que des coupures radio dans le domaine des hautes fr\u00e9quences.
\nVoici deux d\u00e9clinaisons de l’activit\u00e9 de cette r\u00e9gion.<\/p>\n

\"\"<\/a>\"\"<\/a>
\nA gauche, la version ‘normale’ avec les taches sombres et les \u00e9ruptions en blanc. A droite, la version ‘invers\u00e9e’ qui montre, peut-\u00eatre, les d\u00e9tails sous un autre angle.
\nQuelle version pr\u00e9f\u00e9rez-vous ?<\/p>\n\n\n
