Northern US may see aurora Tuesday night

The Northern Lights may be visible Tuesday night in parts of the northern U.S. due to a Kp index of three, offering a chance to see the aurora borealis. The National Oceanic and Atmospheric Administration forecasts the lights will be visible further from the poles, with the best viewing between 10 p.m. and 2 a.m. local time in areas away from light pollution. The forecast indicates a lesser chance for Wednesday and Thursday. This follows recent geomagnetic storms that brought the lights to more states. Increased solar activity, part of the sun's 11-year cycle, has increased opportunities to view the aurora borealis over the last year.
