TORONTO – If you were up early enough here in Canada, you may have caught a glimpse of the northern lights in the early morning sky Wednesday.
A coronal mass ejection – a stream of particles thrown out by the sun – reached Earth early Wednesday morning, sparking the dancing lights.
The Kp index, which is used to measure Earth’s magnetic strength, peaked at 4, which meant that high-latitude sky watchers across Canada were in the best place to catch the lights.
Notanee Bourassa captured a timelapse of the northern lights as they danced across the sky north of Regina, Saskatchewan.
The northern lights, or aurora borealis, were also spotted as far south as Wisconsin, in the United States.
