Solar activity has been at moderate levels today thanks to an M4.5 solar flare from sunspot region 2297 that peaked at 14:33 UTC. This solar flare was impulsive and no coronal mass ejection was associated with the event. A coronal mass ejection visible off the NE limb was likely from a far side event.
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.
