Check out this video of a bright lights hovering in the night sky above Sabino Canyon in Tucson, Arizona. This was taken on 4th July 2015.
Witness report: The very first couple of seconds shows some odd lights in the right of the frame. Those are the radio towers on the mountain out of focus thus making them look odd.
There were a few cars coming and and going out of the parking lot and they account for some of the light shifts. Unfortunately I zoomed in too much and it destroyed the clarity of the video but it still captures the amazing event that we witnessed.
There are a couple of times I adjust the focus and it makes the 3 lights of the UFO seem to morph but that is only, again, me focusing. The main 3 lights stayed distinct in the sky and only look like they become one light and then back to 3 because of my tinkering.
