BOULDER, Colo. — Mother Nature could be set to put on another dazzling show Wednesday night and early Thursday morning with the potential return of the aurora borealis, or northern lights.

A strong geomagnetic storm produced spectacular displays late Monday night and early Tuesday morning, lighting up the northern night sky across Colorado.

The storm wasn’t expected to reach Colorado but several photos were captured, including over Denver International Airport.

The Space Weather Prediction Center in Boulder said another storm is forecast for Wednesday night and early Thursday.

“The coronal mass ejection that erupted June 22 in conjunction with the R2 solar flare has been modeled and arrival is expected June 24 at (5 p.m. MDT).  This timing bodes well for aurora watchers in North America,” the Space Weather Prediction Center said on its website.

“As for the expected intensity, SWPC is continuing to analyze the event and will update the forecast when this analysis is complete.”

If the northern lights appear, they will come in waves, like thunderstorms, and will best be seen from 11 p.m. to 1 a.m. Cloud cover could hamper whether the lights can be seen.

Typical colors are purple and green, but pink and blue hues are not uncommon.

The best potential viewing would be east of downtown and away from the city lights.
