I was taking a break outside the building I was cleaning at 10:00pm MST. The sky was clear to the west, where the sun had begun to set, and as I watched a small line of what appeared to be Jet trail exhaust reflected in sunlight become clear in the sky. It was unusual because there was no other cloud or jet trail close to this golden line looking object. I pointed it out to my work partner and another person who came out of the building at that time. I was a bit fascinated, so I continued to track the object as it proceeded lower on the horizon . When it came closer to the few straggled clouds that had gathered on the horizon, the line changed shape to an orb and disappeared. This whole process took about seven to ten minutes.
