G1 Minor storm conditions reached
published: Tuesday, July 12, 2016 17:49 UTC

G1-Minor geomagnetic storm conditions were reached at approximately 0100 EDT on 12 July (12/0500 UTC). The enhanced conditions were likely a result of the onset of a positive polarity coronal hole high speed stream (CH HSS).  Conditions are expected to last through 0500 EDT on 12 July (12/0900 UTC) as CH HSS influence persists.
