The northern lights should continue well into the weekend and may even reach down into the middle parts of the US.

The agency expects a minor or greater geomagnetic storm—a disturbance of Earth’s magnetic field—on Saturday, which increases the likelihood of northern lights displays being visible to more people, as the effects of a recent coronal mass ejection reach Earth, according to NOAA’s three-day forecast.

The colorful northern lights may reveal themselves to a wide swath of Americans Friday night due to an impending solar storm forecast to reach Earth.
