We propose to compare FUV spectra of bright, quasi-permanent regions of Jupiter's northern aurora using the GHRS with G160M+LSA to search directly for heavy ions in the precipitating particle flux and to determine the effects of strongly precipitating flux on the atmospheric structure. Specifically, we will search for selected emission lines from oxygen and sulfur in various ionization states. The primary objectives of this study are twofold: 1) to investigate the relative roles of ions and electrons as the primary precipitating particles in the Jovian aurora and their energy/flux distribution. This is a prerequisite for understanding the mechanisms which generate these auroral emissions. 2) to examine the effect of intense particle precipitation on the Jovian upper atmosphere. Of particular interest is the extent to which the auroral homopause is elevated as a result of the local enhancement of the eddy diffusion coefficient. This will be determined from the H2 "color ratio" and the ro-vib H2 temperature, which, with modeling, characterizes the hydrocarbon content of the atmospheric layers contributing most to the observed H2 emissions, the pressure level of penetration, and the energy of the precipitating particles. The spectra will complement FOC images previously obtained and permit a symbiotic analysis of both spectra and images.
