Intense Geomagnetic Storms May Bring Aurora to the Southern U.S.
What’s Driving the Auroral Surge? A powerful disturbance in Earth’s magnetic field is signaling a rare chance to see the northern lights further south than usual. Geomagnetic storms occur when charged particles from the sun interact with our planet’s magnetosphere. When these interactions intensify, they light up the night sky with stunning auroral displays. Forecasters…
