Now that is what we call a surprise! Departing sunspot region 2664 which is now behind the west limb just produced an M-class solar flare! Yes, you heard that right. It was an impulsive M1.3 solar flare that peaked at 16:15 UTC. This was the first M-class solar flare since an M5.8 solar flare that took place on 3 April. That is today exactly three months ago!
