Sitting at my sofa that faces a southern big window.It was dark outside.I noticed this ball moving rather quick in a downward arc. There was noglow outside of it,just lit inside with a white light. There is no way i can tell how bigit was or how far away it was. The hole view lasted less than a second.then it was out side of view because of window .I heard nothing. I live on the northern side of Tower Creek canyon facing south. The object moved from east to west as far as i can tell. I had reported it to the UFO reporting site on the internet and they insisted it was a comet or meteorite.I felt as if they were giving mea load of crap!
