The skies are settling down after this week's big solar storm, leaving behind a gallery of green-glowing pictures as a lasting legacy.
For a time on Tuesday, the solar radiation levels registered as the highest in more than eight years, but the most significant impact came in the form of shifts in airline routes to avoid polar disruptions in communications. Strong solar storms have the potential to disrupt electrical grids and satellite operations, but no big problems were reported on those fronts this week.
"Conditions are now beginning to trend back toward quiet levels," the experts at the National Oceanic and Atmospheric Administration's Space Weather Prediction Center reported today. By Thursday, geomagnetic activity is expected to be back down to background levels.
