"Guesstimating" from my location it would appear that the object was very near to, or over Laramie or Cheyenne Wyoming. This was the second best one I've seen in my life as I also witnessed the August 1972 fireball from Provo Utah. Could you please let me know if there are any other reports of this object or if you are able to determine what it was?

Train changed from blue/white as it came off of the object to orange with sparks by the end. It also seemed to split and separate twice (Bolide?) during flight with the smaller pieces quickly disappearing and main object continuing on to disappaer just above the horizon. There was no apparent train visible after the main object disappeared.

Smaller pieces came off of the main object as it flew. It also appeared to separate twice during flight as larger pieces came off but everything that was shed quickly disappeared as the main object continued on.
