The U.S. National Oceanic and Atmospheric Administration (NOAA) predicted the Aurora Borealis would be visible across much of the country on Thursday but it was unclear how much of it could be seen from northern Ontario.

According to their latest forecasting models, there’s a chance Ontario could see the Northern Lights for a second time over Thanksgiving weekend.

The strong auroras in the night sky are because of recent coronal mass ejections, or eruption of solar material, towards Earth. When those electrons reach our planet they collide with oxygen and nitrogen atoms in our upper atmosphere, releasing that energy in the form of light.

In May, northern Ontario was also treated to an astonishing display of the Aurora Borealis.

Cloudy skies and light pollution can impact viewing, so the northern lights are best seen in clear skies and away from major sources of light, such as large cities.

Additionally, Dunlap said the further north you live, the better the celestial show is likely to be.
