Day Three of G1-G2 (Minor-Moderate) Geomagnetic Storms

Day Three of G1-G2 (Minor-Moderate) Geomagnetic Storms
published: Saturday, October 01, 2016 05:21 UTC

G1 (Minor) geomagnetic storms continue as coronal hole high speed stream effects persist. G1-G2 (Minor-Moderate) conditions are expected intermittently over the next 24 hours (29-30 September) as well as more intense activity in the northern latitudes (depicted in the plot above). A G1 (Minor) Geomagnetic Storm Watch is valid on 01 October as effects begin to subside. Stay tuned for updates!
