Solar activity is at low levels with only an occasional C-class solar flare being reported. Sunspot region 2305 which had a couple of delta sunspots a few days ago lost these structures and is now a relatively simple Beta-Gamma sunspot region which is unlikely to produce a strong solar flare. It seems likely that the solar activity will continue to be low (no M or X-class solar flares) in the days ahead as none of the sunspot regions on the earth-facing solar disk right now are capable of producing such flares.
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.
