A minor coronal hole faced Earth yesterday and solar wind flowing from it could arrive in about 48 hours from now. Active geomagnetic conditions (Kp4) could occur once the solar wind stream arrives.
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!
