Storm Watch Details:


INCOMING CME 
•  After months of low solar activity, an Earth-directed Coronal Mass Ejection (CME) erupted from sunspot AR2673 on Sunday. This incoming gust of solar wind is expected to impact Earth’s magnetic field early Wednesday evening and could trigger G1 (Minor) to G3 (Strong) geomagnetic storm conditions, resulting in many hours of active auroras across the North and across Canada. Peak storm activity is expected to occur in the hours following the CME impact. The Space Weather Prediction Centre at the National Oceanic and Atmospheric Administration has issued a 48-hour G1-G3 storm watch that will take effect at 6 p.m. MT on Tuesday, (September 5).
