I was on a Segway tour with my friends in Prague. The sun had just set, and as we were waiting to cross the street, I turned around and snapped this photo of a popular museum. Upon looking at the photo that night, I noticed the circular lights to the right (our left) above the museum. A pair of lights, then a single one, then another pair. And below it another two pairs. I then noticed a small, faint line of lights in a straight line above the museum, leading to what seemed like an identical set of lights to the first, but on the direct opposite side. I tried to debunk this, and pass it off to maybe telephone wires or lightening poles. But I returned to the museum the next evening, and saw no telephone wires, and the lightening poles are much shorter than where the lights appear to be. In fact, you can see them in the photo and how short they are compared to the height of the lights. I'm not sure what this was, or if anybody saw anything else. I wish i had looked at the photo before when I was still standing there. I'm not sure if this is in fact a UFO, or if it's anything at all. I'm hoping you'll be able to tell me.
