KUDAT: A group of photographers witnessed a rare display of lights in the sky here Wednesday night. The dazzling, brightly coloured vertical light pillars — in orange, red, green, yellow and white — danced in the sky for hours. The light pillars started to fade by 1am on Thursday. Light pillars are an atmospheric optical phenomenon which generally occurs in cold, arctic regions. Light pillars appear when natural or artificial light bounces off flat ice crystals floating in the air close to the ground.
