[UVAA] Question about star?comet sighting.

I am hoping someone hear can help me. On Dec. 8th at about 6:25-6:30am, I was waiting for the bus at 2100 south, 700 east. As I looked toward the mountains (east) I saw an enormous star shooting towards the mountains and then fizzling out. It was bigger than what one (myself) usually sees, it kinda came down and floated and then shot faster till it faded out. The was still dark that morning, though with the lights of the streets...you could really see it over the mountains...just amazing! I am wondering if anyone saw this spectacle and if so, can you tell me what time you saw it and what you made of it. thank you very much. Thor
