We are currently feeling the effects of a coronal hole solar wind stream. The solar wind speed increased to almost 500km/s with a fluctuating north-south (Bz) direction of the IMF. Well worth keeping an eye on the solar wind data in the hours ahead as we could see enhanced auroral activity if the Bz decides to turn southward.
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!
