JUNEAU, Alaska—The aurora could be visible across Canada and much of the northern tier of U.S. states — and possibly farther south — Monday night following a major disturbance in the Earth’s magnetic field, a forecast shows.
The forecast, from the National Oceanic and Atmospheric Administration’s Space Weather Prediction Center, comes amid intense geomagnetic and solar radiation storms, said Shawn Dahl, service coordinator at the center.
