Nine U.S. states positioned to witness aurora borealis as geomagnetic activity intensifies

A surge in geomagnetic activity from solar disturbances is expected to push the northern lights southward into the continental United States this evening, making the aurora visible across nine northern and mid-latitude states. The phenomenon occurs when charged particles from the sun interact with Earth's magnetic field and ionosphere, creating the characteristic green and violet light displays in the upper atmosphere. Observers in affected regions with clear skies and minimal light pollution should have the best viewing conditions.
