Bolingbrook Illinois last night, watched this thing flash, what looked like alternating, between white, green, red, and blue.. not really in any pattern. Would be green and white, flashing, kinda alternating between white flashes, then green. Sometimes blue, and red when going down, sometimes. Stationary, then would go down, come back up after a while, maybe move around a little bit, then stationary, then down. Made no noise, wasn’t a helicopter. Currently there are no air traffic lanes above...
