Two Bright lights move slowly over Derby before being joined by a third to form a triangle.Whilst washing the dishes I glanced out of the window and saw 2 very bright circle lights seemingly hovering over the city of Derby. I watched a little while and noticed they were moving very slowly in a North to South Direction. Whilst I watched my wife joined me and I began to take a very short video on my mobile phone. It is very shaky but you can see the lights. As I did this a third light seem to come from a northerly direction and join them. It was like a triangle shape. They then all together moved south and out of our sight. The video I have is only about 14 secs and was shot at 18:09. You can hear quite clearly in the film as I film 2 my wife shouts "theres another one". I haven't reported it until now as I thought it was insignificant until I read the stories about a possible UFO strike in Lincoln, UK on a Wind Farm which is not that far from Derby.
