NOAA northern lights forecast: Northern lights could light up skies across the US and Canada tonight; here's when and how to watch on your smartphone

Northern lights forecast: A minor geomagnetic storm is expected to create favorable conditions for the aurora borealis. Skywatchers in parts of Canada and several northern US states may witness the light show. This event is driven by a fast-moving stream of solar wind from a coronal hole. Viewing conditions matter, so heading to dark locations is recommended. Modern smartphones can capture the aurora, even faint displays.
