At the time of the sighting me and 2 friends were laying on the trampoline looking at stars. we recently saw a satellite and an airplane. we thought the lights were just a satellite but then we saw them changing colors and moving. the aircraft stayed stationary but we saw the lights flashing green, blue, red, and white. they moved in kind of a circle and we continued to watch. I then came inside to get my phone and the aircraft was still there.
