UFO west of Fort Collins, Colorado, November 26 2013First spotted to the west, I was at College and Prospect. It was a bright white light in the sky above the mountains. I ran back in and grabbed my co-worker. She had never seen one before. I actually stopped some people by campus. I ran home and grabbed my neighbors. We went out to see it and watched it for another 10 minutes. During that time, changed from bright white to yellow/gold, occasionally flashed red, grew dim and then bright, lights reflecting off of surrounding clouds. Planes in the sky seem to be unaware of it's presence, we watch one actually fly behind the object and appear on the other side. Started drifting really slow along the horizon and began to drop. Got the car to drive west to try and get a better view. Realized it was dropping behind some hills, took a detour and ran up a hill. It was gone by the time we got there, which was around 7 PM.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information. PD))
