Solar activity reached again moderate levels thanks to a very impulsive M4.3 (NOAA R1-minor radio blackout) solar flare at 13:03 UTC. We also have some disturbing news from NASA regarding the STEREO Behind spacecraft.
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.
