I love this comment from that page:
Me, I’m going with Russian missile with a bad sense of direction.
Reflected in some swamp gas, yes.
What? No weather balloon?
Having read more about it, I’m just wondering if there is any geophysical reason why an event at the collider might manifest over Norway?
So, Hammerfest to Trondheim or so, about 400 miles.
Distance to horizon calculator gives a required altitude of about 100,000 feet for a horizon of 400 miles.
That’s 19 miles high.
That’s pretty low for auroras:
But it’s awful high for an art student with a Kleig light and a laser.
Of course, witnesses have been known to embellish on reality…
Hammerfest News from November 11:
Mystisk lysfenomen i Hammerfest
Strange light in sky, with picture.
It was a Russian missile test, and this week’s light might be more of the same.
The cellphone image from the OP looks exactly like a wormhole opening up, so I"m going with that. This is very exciting. I wonder how long we’ve had wormhole technology?
Too bad they didn’t wait a couple more days. It would have been especially spectacular if the lightshow had occurred on St. Lucia on the 13th.
Early St Lucia miracle anyone?
What do you mean “We”?
Just stumbled across this – I think the Russian missile test is the most likely explanation, and can easily account for the whitish spiral, and the blue part might be the missile going up, already somewhat unstable – though, does anybody have a good guess as to why it’s blue? And does the direction work out? Russia is denying everything, but if this was actually a secret test (Norway apparently hadn’t been informed, as it should have been if this was a test), that’s probably not too much of a surprise.
Here’s another site with a couple of pictures.
Whatever it is, it sure is pretty – I would’ve loved to see it life.
At that latitude? Be serious.
Well, if someone lit your … wait, that’s the wrong joke.
The bad astronomer thinks it is a rocket.
Glad to know a lot of us are in good company. 
Another vote for rocket too from this non-expert in anything. Back in the eighties I remember a “comet-y” looking thing appeared in the sky where I lived in Wisconsin…if I’m remembering correctly, it was a stage of a Japanese rocket “slowly” (from our perspective) falling back to Earth burning up and trailing propellant.
Liquid oxygen is blue. And those pictures are long exposure - it might not have been so blue to the naked eye (the videos I’ve seen don’t seem to show any blue). What is weird is that the blue streak stayed in the sky as dawn came up.
I even took a picture of it. But I haven’t a clue if I still have it.
The blue streak would be an artifact of the long exposure, eg the very faint beam turned blue when captured for a long enough period due to a slight blue hue in the light. When its reflecting off the clouds and moving faster it stays white.
I maintain that to anyone that has worked a lot with professional lighting at that level it immediately looks like a simple gobo (goes before optics)
With a very powerful light source and waiting until there is very high cloud cover it could be seen over a long distance… or alternatively if it was an elaborate prank they could simply have setup projectors in different cities projecting the same thing at the same time so it appeared to be one image.
“‘It was like a giant spiral - a shooting star that spun around and around. I initially thought it was a projector’, added Axel Rose Berg, from Alta.”
This made me laugh.
It’s obviously an Anomaly. Stalker…Get out of here, Stalker!
It’s obviously the Wyrm trying to manifest high above Gaia. Whether it is the Defiler Wyrm, Beast Of War, or Eater Of Souls I cannot say at this point.
