This is a CCD image taken 19 July UT (18 July CDT) at 02:22 UT (9:22pm CDT) with the 0.8m telescope of The University of Texas McDonald Observatory. An 893nm filter which isolates absorption by methane gas was used. This filter makes high cloud features appear bright. North is at the top and west is to the right. 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 locations of two comet fragments are visible as bright spots. The spot due to comet fragment A is on the west limb and the spot due to fragment C is to the east of it. The black spot just below the north polar hood 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).
