Strange light in the night sky.I was on vacation in Crikvenica, Croatia. I was at the Omorika Hotel when I noticed something faintly flickering overhead. I cound not see the shape of the light. I used a DSLR to shoot photos. I had to make 30 second exposures to see the object/light. I can submit RAW files and well as jpg. There was a spotlight coming from the town center, but it crossed the entire sky. After reviewing the photos, I saw that the light looked like an eye or hollow circle, the inner edge was very sharp while the outter edge faded out. After taking the photos, I went to sleep, the object was not there any other night.
