A southern extension of the northern hemisphere polar coronal hole is now facing Earth. It extended far enough towards the south to trigger our automated coronal hole detection system.
A new and unnumbered active region is now rotating into the earth-facing solar disk. It is new active region that only started to develop about 24 hours ago based on STEREO Ahead EUVI footage.
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!
