STORM WATCH

Storm Category: G1 (Minor) to G4 (Strong)
Watch Begins: Wednesday, September 6, 2017
18:00 MDT

Duration: 48 Hours

Storm Watch Details:


ENCORE CME 
•  On Wednesday, September 6, sunspot AR2673 unleashed a major X9-class solar flare – one of the largest in a decade. This intense event was accompanied by a very fast-moving Coronal Mass Ejection (CME) that included an Earth-directed component. Impact from this CME is expected on Thursday evening, adding to already unsettled conditions. As a result, the impact has the potential to trigger G1 (Minor) to G4 (Severe) geomagnetic storms. Observers across Canada should be on alert for active auroras in the hours following impact on September 7, with periods of activity continue overnight as Earth’s magnetic field continues to react to the incoming particles. The Space Weather Prediction Centre at the National Oceanic and Atmospheric Administration has extended the existing 48-hour G1-G3 storm watch initiated on September 6. The revised watch now extends to September 9.

STORM WATCH

Storm Category: G1 (Minor) to G3 (Strong)
Watch Begins: Tuesday, September 5, 2017
18:00 MDT

Duration: 48 Hours

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).

STORM WATCH

Storm Category: G1 (Minor) to G2 (Moderate)
Watch Begins: Tuesday, March 21, 2017
17:00 MDT

Duration: 72 Hours

Storm Watch Details:


HIGH SPEED SOLAR WIND 
•  An unexpected high solar wind stream swept past Earth early on March 21 with the intensity of a Coronal Mass Ejection, setting the stage for elevated geomagnetic activity over the next few days. The Space Weather Prediction Centre at the National Oceanic and Atmospheric Administration has issued a 72-hour G1 storm watch that will take effect at 5 p.m. MDT on Tuesday, March 21.
