There was a trail behind the core of the observed circular centre that covered about 65-70% or the viewable area through the rear window in the upper floor where I was lying on my bed watching TV. The 'fireball' was obvious enough the be seen in the night sky that it drew my attention from the TV and could be seen even with there being a desk side lamp to my immediate right side (approx. 5" inches from the right side of my face.)
