AB: The New Horizons (NH) spacecraft observed the icy Galilean satellites with the Alice instrument during the Jupiter flyby in spring of 2007. Hubble Space Telescope Advanced Camera for Surveys (ACS) far-ultraviolet images of Europa and Ganymede complement the Alice UV spectroscopy at this time. Europa and Ganymede OI 130.4 nm and 135.6 nm emissions were detected. Alice observed Ganymede in eclipse twice, viewing the sub-Jupiter and anti-Jupiter hemispheres separately. The ACS Ganymede images show limb brightened emissions from auroral ovals on the leading and trailing sides, consistent with previous Space Telescope Imaging Spectrograph (STIS) imaging. The ACS Europa image shows a localized emission feature similar in extent to a feature previously observed with STIS. Callisto's FUV albedo spectrum was also observed. Preliminary results will be presented.
