I was standing on my porch looking up at the sky when I saw a what looked like a star moving slowly across the sky. It was a steady glow and made no sound as it moved across the sky. I tracked it across the sky until it disappears accross the horizon. I attempted to film it with my phone but the video did not come out very well. It did not seem to be a plane as the lights did not flash and did not make a noise as it passed by like planes do and left no com trail like planes. Its flight path also was not a straight line it kind curved across the sky. I enjoy watching the sky at night and this was like nothing I have seen before.
