This image was taken with ROKCAM on the University of Texas McDonald Observatory 2.7m telescope in the methane band (2.3 microns) on July 20 2:10 UT (July 19 9:10pm CDT). This filter makes high cloud features appear bright. Seen are impact sites L, D/G, and H. Site L shows some structure toward the southwest limb. Site D/G is toward the central meridian, and H is just coming over the limb. In this image, site L is 10 times brighter than the south polar hood, and site D/G is 5 times brighter than the south polar hood.
This image was made by Dr. Beth Clark (Univ. Texas), Dr. Yongha Kim (Univ. Md.) and Dr. Bill Cochran (Univ. Texas) at the 2.7 meter telescope at McDonald Observatory.
