Solar activity increased to moderate levels thanks to an M1.4 solar flare (R1-moderate) peaking at 04:41 UTC from sunspot region 2268. This solar flare was not eruptive and no coronal mass ejection was launched. Can we expect more flares in the days ahead and how about the geomagnetic conditions?
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.
