 -Comet: 220P McNaught

            
This could be our last
            view of the exploding comet, as it fades back to obscurity after
            haveing huge outbursts in brightness when it neared the closest
            approach to the Sun. A faint streak of a dust tail is still evident,
            and there is a small amount of greenish glow to the comets head.
