Solar storms are bringing colorful auroras across much of Canada and northern U.S. states.
Forecasts from the U.S. National Oceanic and Atmospheric Administration (NOAA) predict the show will be visible across most of B.C., Alberta, Saskatchewan, Manitoba, Yukon, Northwest Territories, Nunavut, Labrador and the northern parts of Ontario and Quebec.
Canadian astrophysicist Dr. Jesse Rogerson explained phenomenon happens when large clouds of protons and electrons gusted from the sun get caught in the Earth’s magnetic field and smash into the atmosphere.
He said these clouds are a result of explosions on the surface of the sun, called solar flares. When they reach our atmosphere, they deposit their energy.
The result is the shimmering, moving light display we see made up of various colours. You can get a variety of colors.
Rogerson said the best way to see the ambient colours is to head somewhere far from major cities with lots of lights.
Shawn Dahl, a service coordinator with the Space Weather Prediction Center in Colorado, said the dazzling display is expected to go on for much of the night and peak in intensity between 7 and 10 p.m. eastern.
Dahl said although the colours are fascinating to see, solar storms like these can temporarily interfere with power grids and disrupt radio and GPS communications.
He recommends those heading out to see the display to stay up to date with their local forecasts.
