The sun's stormy weather is supercharging auroras on Earth this week, due to a series of intense geomagnetic storms triggered by recent solar flares.
On Monday (Aug. 12), the U.S. National Oceanic and Atmospheric Administration's (NOAA) Space Weather Prediction Center (SWPC) detected a severe G4-class geomagnetic storm over Earth at 11 a.m. EDT (1500 GMT) that surely would have amplified northern lights displays across the United States if it had not occurred in the middle of the day.
