Blue fireball lights up the sky over Sweden
People from several towns across the country reported witnessing the spectacle at 9:30pm on Monday night.
The phenomenon, which was seen as far north as Pitea, lit up the night sky in spectacular fashion, producing a bright blue glow which was accompanied by a sudden loud bang.
The culprit, as it turned out, was a bolide - a very bright meteor that explodes in the atmosphere.
"This is something that happens a few times a year," said Eric Stempels of the Department of Physics and Astronomy at Uppsala University.
"Because it can happen during the day, when it is cloudy or far from populated areas, these events usually don't get much attention.
