UFO Sighting in Munich, Bavaria on June 3rd 2015 – Hovering object on the horizon. Changing colours. Weird movement.

Hovering object seen on horizon. It got my attention when it started to glow green. Then stop glowing and appeared again just to glow red this time. Then is started to move to the right quite slow but with instant acceleration. Quite weird. I have to mention that I was drunk and the videos I took show only steady object changing colours. The object then returned from behind the tower which is 600m away from me. Estimating distance of the object ~5-10km. The object changed colour few more times and then disappeared behind the horizon. It would be nice if you could keep me updated if you find more reports of my observation.
