I might not be referring to the same thing, but AB is accessible almost every night depending on where you live. I used to live in the prairies of Canada and every winter if you gaze up at the sky you would see green curtains glimmering in the sky. Not as spectacular as the one posted, but enough to say you've seen them and their graceful shimmer. It is also very easy to snap a photo of them.
Since then, I moved to the western provinces and unfortunately I can't see a thing. But I do understand that the further north you go the greater the lightshow is.
