On the probability that the lights where a 'ghost' lense reflection I went back and took another set of five, from the same positions, with the same camera.
The same lights appeared in some of them to convince me that was the explanation. Lower in the photograph, due to less light more camera shake.(The flash function is 'lost' on my digi-camera). Although I took this around the same time of night, the light has gone from the north at midnight. The nights are fair drawing in, are they no!? Sin be christmas!
Thanks to 'anonymous' for pointing it out!
