People always post really awesome ones and make everyone else jealous, so here's a disappointing one to make you all feel better:

There's a mildly red patch in the middle.

Though it is indeed some kind of light, and the local region is definitely considered Northern, and therefore it's definitely some form of Northern Light, it's quite possible it's not the sort of Northern Light we're aiming for.

It's probably just pollution or a stray bit of light from an event - though maybe I'm too early, and it'll look awesome in a few hours?

[Edit] I've just looked at this photo on my computer and it's far clearer - on my mobile (which I used to take it) the red was a barely visibly smudge in the dark sky.
