This is a CCD image taken 19 July UT (18 July CDT) at 02:23 UT (9:23pm CDT)
with the 0.8m telescope of The University of Texas McDonald Observatory.
An 764nm filter was used.  This filter shows the cloud tops of Jupiter.
North is at the top and west is to the right.  In the southern
hemisphere three white ovals which are not associated with the comet
are visible across the central meridian.   To the south and west
of these white ovals the impact location of comet fragment C
is visible as a subtle dark patch.  Barely visible near the north
polar region is the shadow of the Jovian moon Ganymede.  
This image was taken by Dr. Wayne Pryor (University of Colorado),
Dr. Chan Na (Southwest Research Institute) and Dr. Anita Cochran
(University of Texas).
