It has been quite an eventful day on the Sun with 18 M-class solar flares and even an X1 solar flare. Sunspot region 3936 produced most of these events including the X-flare but also sunspot region 3938, 3939 and 3940 were contributors.
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.
