It was 11.30 on Sunday 16th July when me and my wife were retiring to bed. As I closed the curtains I saw a really bright light in the sky which was just between the houses opposite. It was so bright and shinny that I could not take my eyes off it. As I kept a close eye on it if seemed only to be moving side to side in the same orbit. I ruled out a helicopter or light aircraft as I have seem these many times in the sky and this was just nothing like that. The lights appeared to be all different yellows blues and reds which seem to change into different sequences, I thought a few times that the lights were actually moving around the main light. I did take a video of the light and my wife who is a skeptic could not explain in her usual manner as it was so different. It looked like at times that the lights were displaying shapes with a triangular shape appearing at both sides of the main light. Then this sequence of lights which I was not 100% sure seemed to be being repeated over and over again. It never really moved much although I am sure from side to side along its horizontal path. It got to 00.15 and although I was still fascinated and could have watched it all night just reluctantly retired to sleep. First thing in the morning was to look out of the window but as expected nothing. I will look again tonight when it gets dark and when I get home from work, defiantly between the same time and see if I can find my binoculars. I would expect others to have seen this in MK as it was just so bright and different so will search social media when I get home to see as it was just unreal.
