Sky-watchers in southern Alberta were treated to a spectacle Sunday night, with bright auroras dancing across the sky.
And that’s not all.
One image — featuring an elusive ‘moonbow’ alongside the auroras has gone viral.
“A moonbow is, essentially, a lunar rainbow which is seen at night, as the light from the Moon is backscattered by water droplets or raindrops,” explains Weather Network science writer Scott Sutherland.
“Basically, moonlight is entering one side of a water droplet or raindrop, it is refracted off the inside surface of the opposite side of that droplet or raindrop, so that it exits out of the droplet or raindrop back in the direction from where it came, and then it is picked up by our eyes (or a camera),” he writes.
