Orange light viewed from open window, object came back on itself, stopped and then went away at speed with no noise or change of light.Object:- Orange round shaped fireball/object which looked as though it was being viewed through a haze/mist although the night sky was very clear when spotted. Only one object spotted.First viewed from closed window and thought it was the way a street light was reflecting on the glass, I stood up and realised that the object was in the sky. I moved upstairs to gain a better view and opened the window so that there were no light reflections from the glass.The object was static in the sky at this point and I proceeded to grab my digital camera, unfortunately the batteries were flat so I went to observe the object again through the open window. It started to move in a southerly direction very slow as if a helicopter was hovering but it suddenly came back on itself in a north-westerly dirrection but was hard to tell how high or how far it was moving but was not very far at this point.It then suddenly moved away into a south/south-easterly dirrection at speed, nothing like I have seen from a helicoptor nor a plane with its acceloration.There was no change in its shape, the light coming from it never changed like a commercial aircraft would with its anti-collision light being obscured as it moved but most percular is the fact at no stage was there any noise. Even when it pulled away at speed.There were no extrme weather in the area. Wuite a calm, cold night (roughly 5 degrees celsius) The area is used by the UK RAF as a bombing range at Donna nook but this was definately not a plane, and I do experience flights and contact with helicopters in my rangwe of work and it was again definately not a helicopter.I would if possible like to know what would happen to this report as I just searched in google for UFO reporting to get this, I do not mind being contacted.
