Just to clear up the witnesses thing... I was taking pictures across a bay at night, i did'nt see anything before or after the picture was taken when i reviewed the pitures later i noticed.

I was taking photo's across the bay and i did'nt notice anything strange at all I was using my Digital camera so i was reviewing the picture on the camera's VDU when i noticed just one of the pictures had a circle in it, so i took a closer look across the bay and saw nothing, then dismissed it for the time. When i got home i had a closer look on my PC and was puzzled. I thought it may have been a smudge but it was the only picture with anything + it was a close to perfect circle + the bottom decends below the cliff on the opposite headland. As usual the weather in Sinai was dry, warm and without strong wind. I will send an encompanying Email with the subject Egypt. I am very interested in the answer to this puzzle so even if u take it as a false alarm i would like a reason for this picture, and i am open to any Questions.
