Nature is putting on a show for southern Canadians this weekend, if they're lucky.
Sky-watchers from coast to coast have the rare chance to catch a glimpse of auroras on Sunday night (July 16).
A cloud of solar particles was thrown into space when a solar flare exploded on the sun, The Weather Network reports. The northern lights may be visible in North America as part of this cloud passes Earth.
A map created by the U.S. Space Weather Prediction Centre shows that folks in southern British Columbia, Ontario, Quebec, and the Maritimes have the best shot at seeing the lights.
Auroras are visible when electrons collide with the upper reaches of Earth's atmosphere. The multi-coloured lights can come as arcs across the horizon or as tall rays.
Auroras are unpredictable, and may be bright one second and then faint the next, The Weather Network says. If you live in a big city, light pollution may make them much harder to see.
