The Jupiter aurora in the UV with the
HST/STIS. The three pictures below show the
evolution of spatial resolution offered by HST in
observing the Jupiter aurora. The HST/STIS MAMA
image is the only one showing the trail of the Io
magnetic footprint below the auroral oval (from
Gerard et al. 2003 http//lpap.astro.ulg.ac.be/jup

The continuum spectrum of comets below 300 nm has
rarely been studied. The spectrum seems to be
solar, with a slope of order 10 per 100 nm near
290 nm. Detailed observations of the UV
spectrum of periodic comets are still to be made.
One expects, due to a very different thermal
history, that the spectrum of periodic comets
would be severely depleted in some highly
volatile species, e.g., CO. This can be tested by
detecting and monitoring the emissions of CO and
CO2, or those of C and O when the former are not
detected.

A low resolution (?6 Å) IUE spectrum of comet
Hyakutake. WSO/UV with HIRDES will be capable to
deliver high-res spectra (R?50,000) of similarly
bright comets.
