The strength of the IMF remains at moderately high levels with a steady southward directed IMF (Bz) around -16nT. This caused a significant geomagnetic response during the European evening hours where the USAF Wing Kp reported strong G3 geomagnetic storm conditions and NOAA reported moderate G2 geomagnetic storm conditions. Aurora displays were reported as far south as the Netherlands and northern Scotland even had overhead aurora! A webcam in Hungary even managed to capture some faint aurora!
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!
