What a show! From my vantage point in Cottonwood Heights the fireball started in South over Lone Peak went over head and continued all the way across to North horizon ~30 seconds long, slow moving and fairly bright with long comet like tail and fragmenting sparklers.

persistent train was not easy to see, but there for at least 40 seconds or so, appeared to be a smoke trail that dissipated did not glow but was clearly the line the fireball had taken.

like a glowing sparkler on the 4th of July seemed to fizzle and fragment more at the beginning of sighting then at the end, but could be that it also just got much further away at end of sighting
