"Rare Northern Lights Spectacle Expected in Multiple US States This Week"

The Geophysical Institute at the University of Alaska has forecast auroral activity in 17 states, including Wisconsin, due to a solar storm reaching the upper Midwest. The best viewing times for the Northern Lights are between 10 p.m. and 2 a.m. local time, with better chances of seeing them in northern areas away from city lights. However, visibility may be affected by clouds and rain in southeast Wisconsin. The intensity of the lights varies, and a geomagnetic index known as Kp ranks the activity level, with a forecast of Kp 6 for Thursday's storm.
