The northern lights are best seen between 10 p.m. and 2 a.m. local time while at a high, north-facing vantage point away from light pollution, according to NOAA. Aurora borealis is best seen from late September into early April because of the longer nights, though the phenomenon can still be seen throughout the year depending on solar activity.

A geomagnetic storm will expand visibility of the aurora borealis Thursday and Friday nights. See maps of which states will get to see the northern lights.
