COMMENTS:
A strong burst of geomagnetic storming over the last six hours has
pushed middle latitude geomagnetic indices above the minor storm threshold
at 03:00 UTC. This activity is the result of a high-speed solar wind stream
pushing past the Earth from a well placed solar coronal hole. It has not
yet been confirmed whether a recent confirmed coronal mass ejection may be
contributing to the activity.
Major to severe geomagnetic storming has been reported over many high
latitude regions. Additional minor to severe storming is expected
throughout the local night sectors over the next 24 to 36 hours.
