Weird Spiral in The Sky of Norway

It looks obvious to me someone was playing with a laser light.

"Last night a strange spiral lit up the sky over Norway, from Trøndelag to Finnmark, and many people took pictures.
The phenomenon began when what appeared to be a blue light seemed to soar up from behind a mountain. It stopped mid-air, then began to circulate.
Within seconds a giant spiral had covered the entire sky. Then a green-blue beam of light shot out from its centre – lasting for ten to twelve minutes before disappearing completely."
