Northerners thawing out from a bitter freeze may get rewarded with shimmering northern lights the next couple of days.
The University of Alaska’s Geophysical Institute predicts much of Canada and the northern fringes of the U.S. should be able to see the northern lights. Chicago, Boston, Cleveland, Seattle and Des Moines might see the shimmering colours low on the horizon.
U.S. federal space weather forecaster Joe Kunches said the sun shot out a strong solar flare late Tuesday, which should arrive at Earth early Thursday. It should shake up Earth’s magnetic field and expand the Aurora Borealis south, possibly as far south as Colorado and central Illinois. He said the best viewing would probably be Thursday evening, weather permitting.
The solar storm is already causing airline flights to be diverted around the North Pole and South Pole and may disrupt GPS devices Thursday.
The northern lights are a result of charged particles from the sun interacting with the Earth’s magnetic field. As particles from the solar wind enter the Earth’s upper atmosphere, they collide with the individual atoms of our atmosphere to produce the spectacular light show.
