Solar activity has been at low levels (only C-class solar flares) since the X1.6 solar flare from sunspot region 2205 that occurred 2 days ago. Sunspot region 2205 retains three delta sunspots but did shows signs of decay. There were also two eruptions this morning on the Sun that we will also take a look at.
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!
