M7.3 and X2.2 solar flares

With sunspot regions 2993 and 2994 we have two formidable sunspot regions on the earth-facing solar disk. These regions are fairly stable but did loose some magnetic complexity since they first appeared on the east limb. C and even M-class flares remain possible from these sunspot regions but it is departing sunspot region 2992 that has been stealing the show today. First it produced an M7.3 (R2-moderate) solar flare that peaked at 01:36 UTC which was quickly followed by the strongest solar flare of the current Solar Cycle thus far: X2.2 (R3-strong) at 03:57 UTC.
