The aurora borealis could be seen as far south as Alabama and California on Thursday night, and the surge of solar particles could extend into Friday too.
"The aurora may become visible over much of the northern half of the country, and maybe as far south as Alabama to northern California," NOAA predicted.
A severe geomagnetic storm could disrupt communications and bring northern lights to parts of California, according to a warning from the National Oceanic and Atmospheric Administration.
