This morning (CET), there has been a really angry blast from what appears to be these two active regions coming back into view.

When things like this are visible in SDO's AIA 1600, you know things are serious. I hope weather will permit imaging this week as this, still hidden monster, finally gets back into view.

AIA 304 (30.4 nm). Roughly 10.5 minutes of time separation.

Hi - I'm aware of sunspot cycles, etcetera, and am wondering how often something like those pictured in post #2 happen. Or does it just appear unusual because of the wavelength? Thanks.

I don't know if anyone has calculated how much energy has been thrown out in those 15 minutes, but I'd say it's a serious fraction of daily output. Pretty rare.

That is utterly incredible! Amazing photographic sequence! Inspires to get the scope out and look at that region of the sun today.
