Heads up, aurora chasers! A powerful solar storm is on the way.Space weather forecasters are warning of a strong (G3) geomagnetic storm, with a chance it could reach severe (G4) levels, thanks to a blast of solar material heading straight for Earth.

If the severity holds as predicted, the aurora could be seen as far south as Alabama. But many people may able to see the aurora even farther south using camera lenses, including those on cellphones. Slightly weaker storms that are ranked 3 out of 5 can create auroras that are typically seen only as far south as Illinois and Oregon.
