X9.3 CME impact, Severe G4 storm

The X9.3 coronal mass ejection has arrived at Earth and boy does it pack a punch! While the M5.5 coronal mass ejection turned out to be a huge dissapointment, the X9.3 coronal mass ejection is much stronger than expected and we are seeing some of the strongest geomagnetic storming of the current solar cycle.
