I saw a very bright light going from west to east. I live in Lakewood, CO. The light appeared at 548 pm and was observed until 553 pm. The light was very bright, no strobes or any navigation lights were visible. It was about the size of my finger at arm���s length and was solid white. It seemed to be at about 9000��� and stayed in a linear course. At the end of the observation, 553pm, changed to red and accelerated quickly into space.
