Keep an eye on the skies starting Friday night for what could be a dazzling display of nature — or not, depending on your location and weather conditions.

An unusual amount of solar flare activity means that the aurora borealis (also known as the northern and southern lights, depending on your hemisphere) could appear in the sky as an arc of green light.

If you’re in a place with a lot of bright lights — like a city — it’s going to be hard to see anything. And then there are other complications, like the weather.

The Northeast is likely to be blanketed in clouds on Friday night. In the Midwest, the skies could be clear after a storm system moves through.

With this intensity of solar storm activity, it’s possible the lights could be visible as far south as northern Alabama and Georgia, where night skies are expected to be relatively clear.

The southern Plains and Rockies, however, might have relatively poor viewing conditions.

On the West Coast, conditions should remain relatively cloud-free, which could make for good viewing.
