The three 'lights' in the video were first noticed in the nights sky above Cardiff because there were no stars visible that night and they were aligned . They also were not moving. The viewer then watched on as they moved into a triangular formation and moved across the sky , capturing some of it on camera untill they move out of sight. The filmer reported that they had no blinking lights (although they appear to blink in this footage as the camera goes in and out of focus), were not using search lights and moved very slowly, maintaining the same speed.Each one was only visible as a single orange light.
