Terminal flash
Observation Yes
Remarks I was facing roughly north when the area around me suddenly became illuminated quite bright as though a vehicle with its headlights on was entering the parking area (Cape Royal Point, Grand Canyon National Park) and driving directly towards me. I turned in the direction of the illumination (to my right) and saw the fireball well up in the eastern sky.
Fragmentation
Observation Yes
Remarks There was obvious fragmentation as the fireball streaked downward toward the SE horizon. The event was short, perhaps 2-seconds in length. The length of the fragmentation train was roughly 30-40 degrees. When the event ended, the fragmentation train quickly dimmed. I did not see a remnant glow or indication of a debris cloud in the sky, which was illuminated by a 3rd quarter Moon.
