Many of you have probably seen this amazing photo being shown all over the Internet and TV. It was seen over Norway.
Some of the explanations people are tossing around include:
A failed Russian rocket launch
HAARP (facility in Alaska that probes the ionosphere)
Hadron collider (creating a black hole)
This was seen in Northern Norway and apparently not associated with the Northern Lights. It was said to be a blue light starting from the ground behind the mountains and heading up and about halfway up, beginning to spiral and then left spiralling rings in the sky. This sounds a bit more like a failed test rocket to me, but the effect on the sky was really quite remarkable. We've seen failed test rockets before, but never with something like this...
I'd like to hear your feedback on what you think.
