Both main sunspots of the solar face AR4432 and AR4436 have developed gamma-delta configurations so any of them could emit strong M-class flares like that yesterday but until now activity remains in basal B-class. The pair of big cores of AR4432 can very well complete the backside rotation and reappear at the eastern limb in about two weeks.
