A surprisingly strong geomagnetic storm hit Earth this morning. This is likely the earlier than expected arrival of a coronal hole solar wind stream. The NOAA SWPC reported strong G3 geomagnetic storm conditions and the Wing-Kp as well as Potsdam reported moderate G2 geomagnetic storm conditions. Today's header image comes from the talented Brian Drourr Photography who captured this amazing shot from Algonquin Provincial Park, Canada.
