Aurora Borealis Alert: Where to See the Northern Lights Tonight

The northern lights, or aurora borealis, are expected to be visible in several northern U.S. states, including parts of Washington, Idaho, Montana, and Maine, due to a forecasted Kp index of four indicating increased geomagnetic activity. The best viewing times are between 10 p.m. and 2 a.m., with minimal light pollution and clear skies. This increased visibility is linked to a solar maximum period, characterized by heightened sunspot activity and coronal mass ejections.
