At approximately 6:45pm on December 22, 2008 I went into my back yard to smell the fresh air. I looked up and noticed some clouds and several stars. The stars were moving west and I noticed the Big Dipper. I then saw something that looked like a star moving North. I thought it might be a plane but wondered how high a plane would have to be to look like a star. I lost sight of it for 2 minutes behind some clouds. As the clouds moved I could see it again moving South. Again I thought it must be a flight pattern but I don’t know. I saw only a white light. No red or flashing lights.
