We were out with my friend for a moment chatting and we sat down. Suddenly I looked up at the sky and saw a big bright sparkling light ball moving from left to right for about 3 seconds at the pace of the plane, then it disappeared behind the dark clouds. It was the size of a sun in the sky and had a little red color. I then wondered why I even looked at the sky but I probably saw a light from the corner of my eye and then I looked at the sky. My friend didn’t see it as he sat with his back to that light phenomenon. There was a mystical feeling after the vision of what it was and the first thing that came to my mind was that the UFO was a spaceship, but whatever it was then.
