  • A stunning aurora may be visible farther south than usual this Friday, lighting up the northern US.
  • That's thanks to an overactive, giant spot seven times the size of Earth that's erupting on the sun.
  • Northern border states from Washington to Michigan are most likely to see the aurora Friday night.

For the first time in 20 years, NOAA has issued a G4 geomagnetic storm warning. The Northern Lights are forecast to reach farther south than usual this Friday, dazzling states across the northern US.
