Solar activity has been relatively quiet for weeks now but that came to an abrupt end today as departing sunspot region 4086 which is now close to the west limb produced an X1.1 solar flare (R3-strong radio blackout) that peaked at 15:37 UTC.
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. If you like SpaceWeatherLive and want to support the project you can choose a subscription for an ad-free site or consider a donation. With your help we can keep SpaceWeatherLive online!
