D'après la NASA il y a deux groupes visibles : AR12760 et un un autre groupe (peut être nommé AR12761)
Je ne distingue pas (au travers de mon Canon SX30 IS) le groupe AR12760 mais au contraire j'observe le nouveau possible groupe nommé AR12761.
Classification groupe (probablement AR12761) : Axx
Q : 1 * A = 1
