With solar storms causing a geomagnetic storm on Earth, the northern lights or aurora borealis could extend beyond the Arctic Circle down into the northernmost U.S. states this New Year’s Eve, according to a Dec. 31 forecast by the National Oceanic and Atmospheric Administration (NOAA).
The moderate-strong G2-G3 geomagnetic storm, with a Kp index of 6-7, forecasted for Dec. 31 by NOAA’s Space Weather Prediction Center, means the aurora could be visible in New York and Idaho, and potentially as far south as Illinois and Oregon.
The Kp-index measures geomagnetic activity in the Earth’s atmosphere. “For Kp in the range 6 to 7, the aurora will move even further from the poles and will become quite bright and active,” according to NOAA....
