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.
A lot of people come to SpaceWeatherLive to follow the Sun's activity or if there is aurora to be seen, but with more traffic comes higher server costs. Consider a donation if you enjoy SpaceWeatherLive so we can keep the website online!
