Photos of rare blue and yellow light pillars snapped by Stockholmer Raitis Freimanis have gone viral in Sweden

When Raitis Freimanis, 54, got up early on Wednesday morning in Bromma, Stockholm, he discovered something unusual outside his window. Several tall columns were shining up from the ground, radiating yellow and blue light.
"I was thinking what the hell is this? At first I thought it was a floodlight or something, I thought to myself, why would they put up a floodlight at 5am?" Freimanis told The Local on Thursday.
The Stockholmer said he had been woken by the family's cat and had decided to go and feed the animal. And after seeing the magnificent strange pillars, he ended up getting his son and wife out of bed to see them too, in case they didn't appear again.
Together the family researched what they had seen. They believe that the lights were an optical phenomenon caused by the reflection of bright lights from Stockholm city centre, by tiny ice crystals, hovering in the air.
"It was -13C here in Stockholm and windless, and there were ice crystals in the air," Freimanis explained, adding that it was hard to judge the height of the pillars. The fact that the lights were yellow and blue - the colours of the Swedish flag - appears to have been a coincidence.
