3-4 intensifying lights, under telescope; triangles with color-changing and cycling lightsAt approximately 8:30 mountain standard time, my roommate asked me to come outside quickly. I did, accompanied by our third roommate and a neighbor. What we first saw was not immediately striking, approximately 6 to 8 lights in the sky. These lights were just above the horizon as we were looking in a South-Southeast direction. As minutes passed, however, 3 or 4 of the lights began to grow in intensity. The colors of these lights also seemed to change. At times the lights would fade almost to dark, and at others the lights would almost shine in unison as the objects came closer together. I immediately rushed to get our telescope. After waiting a few minutes for the intensity of the lights to come back, I focused the telescope on the light. What I saw amazed me. In the telescope the light was distinctly recognizable as a triangle shape, almost like a chip, with color changing light traveling around the perimeter in a sort of cycling manner. All three other individuals looked through the telescope and affirmed the same details; triangle, color-changing cycling lights. After a duration of about 30 minutes, the sky went dark. It might be important to note that throughout the sighting, the additional lights were recognizable as the strobes of aircraft. A sound was only present when many of the planes heading in the direction of the intensifying lights passed over our house.
