Sunspot region 3664 is now close to the west limb and quieted down a bit compared to last week. Nonetheless it was the source of an eruptive long duration M6.6 solar flare (R2-moderate) that peaked at 9:44 UTC.
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.
