M9.2 solar flare from sunspot region 2297
Sunspot region 2297 is active again after a relative calm past 36 hours. It produced the strongest solar flare thus far in 2015: a near X-class event that peaked at M9.2 (R2-moderate) around 22:22 UTC. This was a long duration event which means it likely produced a coronal mass ejection. When looking at difference imagery from SDO we can conclude that a massive coronal mass ejection was launched, something the latest LASCO coronagraph imagery confirms.
