Abstract: On June 2, 2016 at 10h56m UTC, a −20.4 ± 0.2 magnitude superbolide was observed over Arizona. Fragments were located a few days later and the meteorites were given the name Dishchii’bikoh. We present analysis of this event based on 3 cameras and a multi-spectral sensor observations by the SkySentinel continuous fireball-monitoring camera network, supplemented by a dash cam footage and a fragmentation model. The bolide began its luminous flight at an altitude of 100.2 ± 0.4 km at coordinates φ = 34.555±0.002°N planetographic latitude and λ = 110.459±0.002°W longitude, and it had a pre-atmospheric velocity of 17.4±0.3 km/s. The calculated orbital parameters indicate that the meteoroid did not belong to any presently known asteroid family. From our calculations, the impacting object had an initial mass of 14.8 ± 1.7 metric tonnes with an estimated initial diameter of 2.03 ± 0.12 m.
