Following weekend solar storms, the Northern Lights may be visible in parts of the U.S.
A coronal mass ejection from the sun prompted a rare, severe solar storm alert, though it was not as strong as last year.
Authorities are monitoring for possible disruptions to high-frequency radio, but the worst is over.
Auroras could be visible in darker, rural areas of Alaska, Washington, Montana, and other northern states.
The sun is at the maximum phase of its 11-year activity cycle, making light displays more common; this active spurt is expected to last through the end of the year.
