Aurora Borealis sightings possible tonight and tomorrow night

Severe geomagnetic storms possible

Northern Lights color the Colorado sky Friday night

DENVER (9NEWS) — 9NEWS viewers sent incredible photos of the northern lights, or aurora borealis, that appeared Friday night.

The aurora borealis is a natural light display in the sky, primarily visible at high latitude regions around the Arctic and Antarctic. It is caused by the interaction of charged particles from the solar wind with the Earth's magnetic field.

The intensity of the aurora can vary depending on the strength of the solar wind and the Earth's magnetic field. During severe geomagnetic storms, the aurora can be visible at lower latitudes, such as Alabama and northern California.

The last storm of this magnitude was in 2005, 19 years ago. As a result, the northern lights are expected to be visible in many parts of the country tonight and tomorrow night.

To see the aurora, you need to find a place with dark skies and no light pollution. The best time to see the aurora is typically between 10 p.m. and 2 a.m.

If you're lucky enough to see the aurora, it's an unforgettable experience. The lights can dance and shimmer across the sky, creating a beautiful and awe-inspiring sight.
