According to the Web site SpaceWeather.com, the light display was caused by a coronal mass ejection, or solar eruption, that took place Monday afternoon.
Once the sun set, the effect of the ensuing geomagnetic storm was visible over much of North America.
The storm is reportedly subsiding, but sky-watchers to the north could see lingering auroras tonight.
