long-lived

AR4432, at upper right, keeps producing C-class flares at high rates, at least 14 the last day. It continued growing and now stretches about 6 Earths wide (without foreshortening correction). AR4436, former AR4419, on the other hand has returned to its "birth" place after rotating for 26 days around the sun, its magnetic configuration is currently beta class, so stable
