M6.9 coronal mass ejection arrival
The M6.9 coronal mass ejection has arrived at the ACE satellite. First signs are looking promising for enhanced auroral conditions as the direction of the IMF is cooperating. It is currently directed southward and occasionally dipping below -10nT. A minor G1 geomagnetic storm watch remains in effect as the solar wind and IMF parameters are promising.
