Obtained under poor transparency until clouds rolled in. Only one low quality UV image was grabbed. For IR,three filters were used,IR>685nm,820-920nm (z'-s') and 950-1050nm (Y'). Two gif animations,one for IR685 and another for Sloan z'-s' are attached,showing features rotating with the atmosphere. A dark linear latitude oriented feature (near the equator and terminator) is arrowed in some images. Also,the putative IR visualization of the CD is presentes between arrowheads near the limb. This putative CD region appears UV dark. With the Sloan Y' filter contrast is lower,but the putative CD area and the latitude-oriented linear feature remain visible.
