Went for a walk between Palace Hellbrunn and the Zoo of Salzburg with my girlfriend and took a picture of the mountains in the distance.

At home I looked at all the pictures from that day and saw that there was an UFO in one of them. I couldnt see of hear it while taking the picture. The surface of the object is reflective and covered in shadow on the below.
