The best time to try and see the northern lights is between 10 p.m. and 2 a.m., according to NOAA. If you’re hoping to see the lights, the best visibility will be from a spot pointing north that’s away from city light pollution, NOAA suggests. It should also ideally be at a higher altitude, such as on top of a hill.

The National Oceanic and Atmospheric Administration said geomagnetic storms may occur this weekend, leading to strong northern lights shows.
