I was about to go out onto the balcony for a cigarette and as soon as i stepped outside i observed around 10-15 glowing orbs ranging from red, yellow, green and blue. I had no idea what they could be and called my girlfriend to quickly come and look who also saw them until they were out of sight. The light flew / floated from left to right ober quite a large distance before vanishing out of sight behind the trees and depth of sight. We both have no idea what we saw and are overwhelmed. The video and pictures are not the best. Taken with iphone 5c.
