Jupiter Science Results - Supporting Observations

An important accompaniment to the flyby was a set of supporting observations carried out by ground-based observers, particularly those involved in the Jupiter Watch programme, as well as observers making use of Earth-orbiting spacecraft including the Hubble Space Telescope (HST) and the International Ultraviolet Explorer (IUE). Using ESA's Faint Object Camera onboard HST, European scientists obtained an image of the polar aurora surrounding Jupiter's north pole just 15 hours after Ulysses' closest approach (Fig.10). This type of remote sensing of emissions from Jupiter's auroral regions, and the IPT, has helped to establish the context in which the flyby took place.
