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.
