It took a long time but finally sunspot region 2443 seems to deliver. This earth-facing sunspot region produced at 13:52 UTC a long duration M3.7 (R1-minor) solar flare.
Geomagnetic conditions remain at the minor G1 geomagnetic storming conditions due to the high solar wind speed and a minor southward Bz component of the IMF.
A lot of people come to SpaceWeatherLive to follow the Solar activity or if there is a chance to see the aurora, but with more traffic comes higher costs to keep the servers online.
