The NWS/NOAA Space Weather Prediction Center is the governmental agency tasked with keeping track of solar storms and there is a doozy bearing down on us tonight!! They are predicting a G4+ solar storm. As you can see from the graphic below, storms above G4 intensity are exceptionally rare so try and get outside tonight!!
