Solar activity increased surprisingly to moderate levels. Sunspot region 2182 was the source of three low-level M-class (R1-minor) solar flares today: M1.3 at 01:43 UTC, M1.4 at 01:58 UTC and M1.2 at 06:59 UTC. The solar flares were all rather impulsive and coronagraph imagery from SOHO/LASCO confirm that there were no coronal mass ejections associated with these events.
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!
