Transcript

STEVE INSKEEP, HOST:

And that smiley face could spell danger for us. Those areas have high magnetic field activity, which could disrupt telecommunications in the worst-case scenario. The face cannot be seen with the naked eye, so please don't try to stare at the sun. It's MORNING EDITION.
