AB: Each of the Galilean satellites of Jupiter has an electrodynamic interaction with Jupiter's magnetic field, due to their motion with respect to the corotating field which sweeps past each satellite. With the exception of Callisto, these interactions can be observed via auroral emissions from the magnetic footprints of each satellite in Jupiter's atmosphere, and also via auroral emissions produced in the satellite's atmosphere. Remote sensing observations from the JIMO spacecraft could provide measurements of these auroral emissions with excellent spatial resolution and time coverage, strongly complementing in situ plasma and field measurements near each satellite. The measurement of the auroral emissions at both ends of the field lines threading each satellite would provide important constraints on the nature and strength of the interaction. Extended time series made possible by remote sensing would reveal the variations of these emissions with the location of each satellite in Jupiter's field and the corotating plasma. The time coverage would also provide a baseline for the interpretation of the in situ measurements, which measure one location at a time. The prospects for this remote sensing by JIMO will be explored based on information from the Hubble Space Telescope measurements of Jupiter's auroral emissions.
