“It consisted initially of a green beam of light similar in colour to the aurora with a mysterious rotating spiral at one end,” said another eyewitness, Nick Banbury of Harstad, quoted on Spaceweather.com. “This spiral then got bigger and bigger until it turned into a huge halo in the sky with the green beam extending down to the earth. According to the press, this could be seen all over northern norway and must therefore have been very high up in the atmosphere to be seen hundreds of km apart.”
