This program conducts solar system research in support of NASA missions and of general astronomical interest. Investigations of the composition, physical characteristics, and changes in solar system bodies are conducted primarily utilizing facilities of McDonald Observatory, but also utilizing various space vehicles where appropriate. The first detection of 2 micrometer II2 emission from Jupiter's southern auroral zone was made. Previous detection of northern auroral emission from Jupiter's H2 S(1) quadrupole line at 2.12 micrometer was confirmed. Unlike the previously known 8 micrometer aurorae, this phenomenon can not be thermal in origin. Analysis of Raman scattering in the blue and ultraviolet spectrum of Uranus (200 to 500 Angstroms) show that there must be absorbing aerosol particles in the upper 10 mbar region of the atmosphere. Spectra of Pluto-Charon in and out of eclipse in the red and near IR were obtained. These data confirm that CH4 is confined to Pluto and absent on Charon.
