hidden activity

several big dark cores still seen in the sun face, activity is low but... yesterday, september 6th, a full halo CME was produced on the farside as noted on the Sun section; there is indeed a big active region inferred by helioseismology at the backside which should rotate the limb in about 7 days from now
