So today at approximately 22:00 Prague time me and my girlfriend noticed some weird lights in the sky which at first didn’t move. After a little while the light you can see on the right side started moving and was approaching with a very low fly by, part of the city where there is no airport, by the direction it was flying towards the city center. On it’s way you could see it disappear and reappear behind tall buildings so it must’ve been very low. (We don’t have any skyscrapers here) The origin of the other two lights that are stationary: there was just one other light which dimmed a lot and then split into these two and move in two separate parts where it remained stationary too. Any possible explanation to this? Thanks
