October 29, 2005: Taken with a Phillips TOUCam Pro through a C14. The luminance channel was taken through an IR Pass filter to reduce the effect of atmospheric turbulence. North is up in the picture. The south polar ice cap is nearly gone, there are some clouds near the north pole. The Hellas basin, Syrtis Major, and Minor and many other surface features are visible.
