Coronal hole faces Earth
The geomagnetic storm which was the result of a coronal mass ejection impact from the M9.8 solar flare has now subsided. The north-south (Bz) component of the interplanetary magnetic field is pointing northwards which is preventing any kind of geomagnetic unrest at the moment. We did peak at the strong G3 geomagnetic storm level which caused some very nice auroral displays at lower latitudes than usual. So does that mean we need to wait for weeks and weeks before the next geomagnetic storm? No! A very large coronal hole is currently facing our planet sending a high-speed solar wind stream towards us.
