NOTE: Titan's Atmosphere in Late Southern Spring Observed with Adaptive Optics on the W.M. Keck II 10-meter Telescope

Using adaptive optics on the W.M. Keck II telescope we imaged Titan several times during 1999 to 2001 in narrowband near-infrared filters selected to probe Titan's stratosphere and upper troposphere. We observed a bright feature around the south pole, possibly a collar of haze or clouds. Furthe...
