Northern lights are expected in the U.S. skies tonight. A strong geomagnetic storm triggers the spectacular celestial display, with isolated periods reaching G4 (severe) levels.
The Aurora lights will be visible across 23 states from Thursday evening into early Friday.
The National Oceanic and Atmospheric Administration (NOAA) issued a G3 (strong) geomagnetic storm watch, with isolated periods reaching G4 (severe) levels. This phenomenon occurred due to a combination of solar disturbances, including a coronal mass ejection on May 30.
