Sunspot region 3697 has been relatively quiet the past few days as she made her way towards the west limb but she was not planning to exit stage right without one final song. At 01:49 UTC this night the region produced a highly eruptive long duration M9.7 (R2-moderate) solar flare.
A lot of people come to SpaceWeatherLive to follow the Sun's activity or if there is aurora to be seen, but with more traffic comes higher server costs. Consider a donation if you enjoy SpaceWeatherLive so we can keep the website online!
