A severe geomagnetic storm (G4) is predicted for Sunday night into Monday due to a strong coronal mass ejection from the sun. This could cause disruptions to communications and significantly increase the chances of widespread aurora borealis sightings across the US, including the Pacific Northwest. Clear skies are forecast, improving viewing opportunities. NOAA's Space Weather Prediction Center is monitoring the situation and providing updates via its website and experimental Aurora Dashboard.
