I was out for a little walk in the "lüneburger heide" (german national park) with two reletives of mine. we were watching an interesting, but non-relevant cloud formation when one of my reletives noticed a very small sphere right next to it. it was so small, we could barely see it with the naked eye and it appeared to either be reflective or glowing. my relatives thought we were seeing a wheather-balloon while i emediately thought it was an ufo. the object remained sitting static in the air untill a cloud moved between us and the object about 10 minutes after we had noticed it, blocking our view. this was how we lost sight of the object. i tried to snap a couple pictures with my smartphone, but the object was so small that it is pretty difficult to make it out in the picture, with enhanced brightness and contrast however you can see a little blurry thing.
