So while there's no guarantee, there's definitely a chance they'll be visible across parts of North Texas again tonight. When visible, the Northern Lights may appear as pink, purple, green or even red glows that ripple across the sky. Some North Texans who spotted them earlier this week described a faint pink haze stretching over the horizon.

Auroras may be visible from Alaska to Iowa as an incoming flurry of coronal mass ejections could spark geomagnetic storm conditions overnight.
