Geomagnetic storm reaching G2 - Moderate levels in progress

Geomagnetic storm reaching G2 - Moderate levels is currently in progress due to continuous influence from a positive polarity coronal hole. This influence will decrease over the next couple of days, however, the Coronal Mass Ejection (CME) associated with the M3.9...
