Three lights in a triangle that flew off in opposite directions at an amazing speed in Northern Colorado.On the evening Tuesday December 4th I was driving home from Fort Collins Colorado to my house near Nunn, Colorado. It was approximately 7pm. I was on Weld County Road 100, approximately half way between Wellington and Nunn Colorado.I glanced to the south and saw three strange lights in the sky. They looked a bit like stars in the sky but were much brighter, and there were not many stars visible at that time. The lights were arranged in a triangle pattern.My first thought was it was just the lights of the large radio towers south of my house. (Weld County road 27 and Weld County Road 90). I was driving so I pulled over to the side of the road. Once I was stopped I was able locate the red lights of the radio tower and they were NOT the three mysterious lights that I was seeing. The lights were higher in the sky and further west then the radio tower lights.I watched the lights and I was trying to grasp what they could be. Nothing in my mind fit what I was seeing. They were not stars, they were not earthly aircraft. As I stared with amazement the lights, which had been stationary in the sky, spun in the sky together in a circular motion two full revolutions then the three lights took off in different directions from each other. The speed at which they exited my view was faster than anything I have ever witnessed.I waited about 2 minutes to see if I could see them again. I did not. I am not sure what it is that I was looking at, and I have done some simple google searches to see if there others that may have witnesses what I did. I have found nothing.
