UFO Over Mountains In Romania Caught By Photographer By Accident, April 2015, UFO Sighting News.
Location of sighting: Lasi, Romania
Source: MUFON #80180
I didn't include the other photos from the witness because tehere was nothing there, but he did have 3 other photos of the same mountain, but the UFO was gone. So its safe to say the UFO was moving very fast. So fast that the UFO has a smudge on its right side, which means it was traveling from right to left of the mountain top. Again, the UFO looks like a cloud, but mind you, the other photos at the source confirm it was moving lighting fasts and got caught purely by accident. Its a perfect disk, but smudged from high speed.

I was taking pictures, at 1 sec. interval, one after another. At home, I saw the object in the picture. You will see all photos date ant time in the EXIF of the pictures. It's not dust on the sensor, I'm a photographer.
