During the process of putting things away in my new upstairs apartment I looked out my window and I saw a 10' tall object suddenly appear about 100 feet from my window. When it stopped it made very fast pendulum type movements. It looked like a 4'in diameter multi-colored ball with a 6' multi-colored stick coming up from the center of it. In 3 seconds it flung out upward, and disappeared into outer space. I never heard a sound.
