Second strongest storm, M6.6 CME analysis

We are still very much under the influence of the 21 June coronal mass ejection that arrived yesterday evening. The NOAA SWPC reported that the severe G4 geomagnetic storming threshold was reached and the Wing Kp-index even went up to Kp9 which stands for extreme G5 geomagnetic storm conditions, but the G5 reported by the Wing-Kp is questionable. The disturbance storm time index (another way of classifying geomagnetic storms where a lower number means a stronger storm) reached -195nT (for now at least) which makes this the second strongest geomagnetic storm of this solar cycle. The 2015/03/17 geomagnetic storm remains the strongest storm of this solarcycle with a Dst of -221 nT.
