my children called out to me to check out a strange light in the night sky, passing by our home at some distance over the ocean. I saw a rather little and wobbling, rather slow moving light, heading in NE direction which is very unusual around here, as it also moved at a relatively low altitude. I managed to take just 1 picture as the light suddenly disappeared.I was very surprised as I checked out the picture (zooming in), to see a kind of light track produced by the light due to the shutter speed of 0,8 sec, which also showed a circular, disc-shaped object, seemingly moving in a more or less erratic way, changing position all the way through.Hope this picture can shed some light on aero dynamical behavior of UFO's.ps.
