Geomagnetic Storming may be Possible about 4 June

Geomagnetic storming is possible next weekend. A returning coronal hole high speed stream (CH HSS) is likely to rotate into an Earth-influential position beginning around 4 June. This recurrent CH HSS was responsible for the 8 May (Mother's Day) storming, when over 24 hours of G1 (Minor) to G3 (Strong) storming occurred. Forecasters will continue to analyze this feature and determine if Watch conditions are warranted as it rotates into better view. Keep informed as it gets closer to 4 June, by checking our website for the latest forecasts, updates, and information.
