Filmed 5.25pm on 1st Feb 2015 from Kinlochard, Scotland, looking South South West. Very bright large white (reddish) light moves across sky above hills. Filmed for over fifteen minutes this was definitely not a Chinese lantern (too large, too bright and too long in the sky), aircraft (No flight path and too low and slow) or helicopter (would have seen usual flashing green/red lights and heard something but object was silent plus the way it moved tells me not this type of aircraft). It moved slowly and silently. It went behind forest trees on top of the high hills which are approx one mile away and still appeared to be quite a bit further than this but even though it was some distance the size from where I was filming still appeared to be large and very bright. Judging distance and approximate location I would say that it was going over or flying close to Loch Lomond (Here is a rough idea where it may have been flying over: Grid ref – NS 39750-97783, Latitude:56.145741 Longitude: -4.5809916). Although it flew over a remote area of the Trossachs National Park others must have seen it and probably with a better view. Would be good to know what this was and if anybody else got to see it. So to re-cap, the object was large, was emitting a very bright white light with some red light also seen and looked at times to be pulsating. It moved silently and slowly and although I had filmed it for about fifteen minutes it would have been in the sky for longer but I had only noticed it as I was closing the curtains which is when I began to film. There is some blurring and camera shake on the film as I set the camera to manual focus and also to keep continuity of recording I carry on filming as I go upstairs to get a better view of the object.
