High signal-to-noise spectra of the Jovian aurora obtained at 1200 to 1500 A by the IUE Observatory were examined for the existence of sulfur and oxygen emissions that would be expected if the UV emissions were produced by precipitating heavy ions. The results of these measurements and subsequent spectral modeling, using a model of heavy aurora constructed by Horanyi et al. (1988), showed mixed evidence of the oxygen and sulfur emissions. It was noted that only the UV emissions which are produced above the UV absorbing hydrocarbon layer were observed by the IUE and Voyager UV spectrometers. This fact, combined with the recent observations of the longitudinal distribution of the Jovian UV aurora, indicates that electrons as well as ions play a role in Jovian auroral processes. Based on the observations, it is suggested that heavy-ion auroral energy deposition is concentrated at altitudes below the homopause, while electrons with energies of 10 to 30 keV are responsible for the bulk of the observable UV and EUV emissions.
