Increasing solar activity, waning coronal hole effects

Solar activity has been low the past few days but we could be in for an uptick thanks to rapidly developing sunspot region 2230. Here at Earth we remain under the influence of coronal hole high speed stream effects, but these effects are now slowly subsiding. The strength of the IMF maxed out at 25nT during the onset of the coronal hole stream and the solar wind speed managed to reach an impressive 800km/s. Gorgeous auroral displays were seen from many high latitude locations including Finland where Salamapaja took this stunning image of an auroral display above the frozen Baltic Sea and the city lights of Oulu.
