I work on Sundays and was preparing to leave for work. I noticed in the sky a dark dot, which i thought could be a balloon or nothing important.Few minutes later, I looked at it again and saw it ascend in a very unusual way, kinda like a jellyfish swimming, then it stopped again. Decided to grab my binoculars and take a look. At first when I observed the object it seemed like an upside down V. There were clouds nearby that seemed to project shadow on the object. I had to give attention to my dog for a couple minutes. When I observed the object again it seemed closer, and out of the cloud's shadow. Now it looked like a gray colored triangle with a white round bottom. My wife saw it too, but she didn't want to look at the binoculars. It wobbled, then went hovering from right to left and entered a nearby cloud. After that I had to leave and could not observe the object anymore. I researched all similar sightings I could find and the most similar to what I saw was one sighting from Kassel, Germany on June 26, 2014. That really looks like to what i saw that day. Decided to report to MUFON after that. Sending the picture of the Germany sighting for reference. Could not take a picture with my cellphone, the object would not seem to appear.
