published: Tuesday, February 16, 2016 21:19 UTC

G1 (Minor) geomagnetic storm levels were observed at 1159 UTC on 16 February (02:59 AM Eastern) due to the arrival of the anticipated co-rotating interactive region in advance of a negative polarity coronal hole high speed stream. G1 Minor storm levels are likely during the remainder of today (16 Feb) and into tomorrow (17 Feb). Stay tuned for updates!
