Sorry Vulcan! I didn't read the other stories linked to this article.
The article mentioning the 77 year old can be found here:
-http://www.aftenposten.no/nyheter/iriks/article3552964.ece
The article says that on Friday evening Ole Johan Hansen saw a mysterious light in Arnavågen in Bergen. The next morning a beautiful and unexplained pattern had appeared exactely where he saw the lights.
He didn't think the ice was safe, so he took out his binoculars and had a look over the lake, but couldn't see anyone. The light that he spotted was about two meters long and didn't look like anything he had seen before.
During the night a symmetrical pattern had appeared on the ice. The pattern comes from eight holes on the ice. According to Hansen, the rings measures about 50 meters towards northeast and 300 meters in the other direction.
A meterologist admits that he was thinking of something supernatural when he saw the pictures, since they resembled crop circles.
John Halvor Sæle thinks the rings could be created by a meteorite, since they are too far from land to be manmade.
Astrophysicist Knut Jørgen Røed Ødegaard confirms that this pattern could have been created by a small meteorite. He thinks this is unlikely though, since a meteorite would have been spotted by more people and would have appeared as a glowing stripe on the sky before ending up in Arna.
He also says that the light couldn't have come from a meteorite, since a meteorite which lights up on impact would have had the power of 1000 nuclear bombs in which case Bergen wouldn't have existed today.
The article also mentions the light could have appeared from ice fishermen, but there aren't any tracks in the snow and also that the light could have come from street lights from the other side of the lake, but there wasn't any light the following evening.
The comment which stands out the most is from Ødegaard. He says that he thinks the pattern appeared from ice fishing and that the concentric pattern appeared from the tides. He says that it isn't unusual even though they
never get to be as symmetrical as this one.
Edit: Sorry it's in third person. As a Dane I can understand Norwegian, but I can't translating it word for word.
