Triangular/Chevron of three white lights flew extremely fast East over ERAU in Prescott, AZAs I was driving on the west-most side of the Embry-Riddle Aeronautical University Prescott campus, I saw light in my peripheral vision and quickly looked up to my left out the driver's side window. I saw a strange grouping of three soft white lights moving at a VERY high speed flying east straight overhead over the campus. The strangest thing was that I hadn't heard any roar of engines or a sonic boom from the speed. I called an associate, who I knew was out walking nearby, to ask if he'd heard or seen anything, and he denied that he had. It didn't look like any of our planes, and I called the flight supervisor ~21:06 to ask about any planes on the radar, and he said they hadn't tracked anything. The grouping of the lights suggested either a chevron shape, or a formation that was very precisely close at such a high speed. I will assume it was rather close to the ground, as I only saw it for a few seconds before it was gone over the dorms, and the lights were roughly the size of a child's size fast food drink lid held at arm's length, to my perception. (That's all I have nearby to compare it to, don't judge.) I couldn't see any outline past the lights, only the haze of the low clouds fuzzing out the lights a good deal. They moved uniformly for as long as I saw them, giving me the impression it was a single craft. As this is an aeronautical school, there were at least several student pilots within a few miles, but the flight supervisor said no-one else had reported anything. I'm a healthy 22-year old male, with no alcohol in my system. and no history of seeing UFOs nor hallucinating.
