Now that was an intense one and a half week if you ask us! Sunspot regions 2887 and 2891 really kept us all on our toes. M-flares and of course the X1.0 solar flare that looked really promising with an earth-directed coronal mass ejection. But we all now how that turned out. The plasma cloud only gave us a minor glancing blow and we never got the strong G3 geomagnetic storm that was forecast. Good thing we had sunspot region 2891 waiting in the wings.
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.
