At 00: 07 local time a security camera at the high altitude W.L. Eccles Observatory (2930 m above sea level) recorded a movie of the passage of the object to the north . Of particular note in this video is the spherical "ghost" image slightly trailing the main object (this is likely a lens reflection of the intense fireball), and the bright fireball explosion associated with the breakup of a substantial fraction of the object . An object trail can be seen to continue northward after the bright fireball event . The shock from the final breakup triggered seven seismological stations in northern Utah; a timing fit to the seismic data yielded a terminal location of the object at 40.286 N, - 113.191 W, altitude 27 km . This is above the Dugway Proving Grounds, a closed Army testing base . </Dd> </Dl> <Dd> A large bolide was reported on 18 November 2009 over southeastern California, northern Arizona, Utah, Wyoming, Idaho and Colorado .
