object was very round and the size of a baseball if you held that in your fingers looking toward the sky. It was bright yellow on the face (very much on fire) with an orange flaming tail that was say 2 feet long in comparison to if you attached the tail to the baseball. When the object fully passed by us we could see the flaming tail but not the fiery face and it must of flamed out or perhaps broke apart when it was far to our right. It never seemed to get any lower in the sky. It was impressive to say the least. I didn't hear anything about it here in Denver but would like to know more about it. Dan
