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.
