I was mistaken about the event. Apparently it all went on between October 18 and end October, as sunspot AR 12192 rolled across the earth-facing part of the sun, and people are expected the sunspot to come back into sight in a couple weeks. It is the sunspot which is huge, not necessarily its flares. None of the flares it released so far were worrisome.

There's some interesting time-lapse footage at http://www.cnet.com/news/watch-a-timelapse-of-sunspot-ar-12192-in-glorious-hd/ and NASA's news is at http://www.nasa.gov/content/goddard/tracking-a-gigantic-sunspot-across-the-sun/#.VGHAF4h4WrU

PBL Apparently there were 6 X-class flares and 4 M-
