Golden triangle of lights in Northern Arizona, 2 min duration, silent and then just disappearedI was walking North between buildings at our ranch 30 miles NE of Flagstaff, AZ, when I saw three bright amber/gold lights in a triangular formation about 10-15 degrees above the horizon. They were straight ahead of me, and although I couldn't really estimate their distance I guessed that they were a few miles away. I first assumed that they belonged to military aircraft flying in formation, since they were in a patch of sky that was too light to see stars, and they were brighter than any stars and an unusual color that I don't recall ever seeing in the sky before. I watched the lights for a full minute or two. They possibly had red or green flickers, and my rational mind was thinking that these could be additional small lights. I was thinking at the time that the formation moved very slowly, since planes always move, but looking back I'm not sure it moved at all. After this minute or two, as I watched with mild curiousity, the lights just vanished. I figured.... um.... well, the planes must have turned to an angle where I couldn't see the lights any more. I kept watching but they never came back. The desert was totally silent all this time.
