Spiral over Norway

As you may or may not have heard, some bizarre shit happened in the sky over Norway. There are multiple photos from multiple locations showing this thing, which means it can be roughly triangulated to estimate altitude and size. Take multiple photos of it from different locations, look up how far said locations are apart, estimate how many degrees the spiral center is above the horizon in each photo, and there you have it.

I'm curious what you come up with.

spaceweather.com has something about it on their front page, and it links to several news sites from Norway. Site #3 has a photo gallery.

I think russians were trying to kill the nigger
