UFO photographed in the sky over Germany

A strange object was photographed in the sky near the town of Ambach in Germany. And the object was not visually observed, but was detected later when viewing photographs.

The author of the photo checked the rest of the pictures taken from the same angle and at the same time to make sure that it was not a glare and it turned out that there were no objects in other photographs taken at the same time. The photographer is sure that this is not an artifact of the image and not a glare.
