Technically its a sunpot group/region if you get into the nitty gritty of it - even tho they are all obviously related. Also the morphology and evolution of a sunspot group/region dictates its classification too I think? - when it was simply sunspot group 798 originally it was only classed as capable of M-class flares when it came back around it was capable of X-class flares - why spaceweather is still calling it 798 i am not sure - it must be an ambiguous situation
btw Nice catch Ving
like that filter dude
