I went outside for a cigarette, and was looking at the stars, I noticed one really bright star (just checked and it is west of Orion at 7:12pm). When I was looking I saw what I thought to be an airplane, I watched it for a minute and didn't see the normal flicker of lights that an airplane would have. I kept watching it and called my wife out to see it as it kept moving east. She came outside and I told her that it could be the ISS or a satellite. It was moving in a straight line, She and I were looking at it as we noticed it became significantly dimmer, and then slowly faded out of sight within 3-4 seconds.
