The colorful northern lights occur when cosmic rays, solar wind or plasma ejections from the sun hit the earth's magnetic upper atmosphere, according to the Space Weather Prediction Center in Boulder, Colorado.

That same agency says last night storm was considered "severe" and ranked it a 4 on a 5-point scale. The scientists predict another solar storm for Wednesday night into Thursday morning with the possibility of another light show.

"This timing bodes well for aurora watchers in North America," the agency says in a press statement.
