A coronal mass ejection has arrived at our planet. This is likely the arrival of the coronal mass ejection that was launched during a filament eruption in combination with an M3 solar flare two days ago.
Sunspot region 3229 does it again this time with an M6.2 solar flare that peaked yesterday at 19:44 UTC. This long duration solar flare was again highly eruptive just like the M3.7 solar flare. A minor S1 solar radiation storm followed as a result of this eruption which has minor impacts on HF radio communications at high latitudes.
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.
