There was more than one, they were all Orange in colour about the size of a Helicopter, they were like round balls, one of the objects light went from bright to dim very quickly.

There appeared to be about 6-7 all the same size, all going the same speed, all in the same formation and all going in the same direction. The thing that made it strange was that there was no noise, but there was the sound from an aircraft going away from the objects, if they had been helicopters there would have been some sound, these were completely silent!
