Two M-class solar flares
More than three months. That's how long it took for the Sun to boost solar activity up to moderate levels again. It was sunspot region 2567 which produced two M-class solar flares early this night. First an M1.2 (R1-minor) solar flare at 00:46 UTC which was quickly followed by an M1.0 (R1-minor) solar flare at 01:49 UTC. These are the first M-class solar flares since the M6.7 solar flare that took place on 18 April.
