5. Abstract

Over the past decade, the Hubble Space Telescope has acquired an impressive imaging
dataset of the UV aurora of Jupiter. Signatures of the local energy deposition from
energetic interaction processes with the magnetosphere, when viewed as whole, the
patterms of emissions seen in these images are mirrors to the global state and
configuration of the magnetosphere resulting from the most recent interaction with
the impinging solar wind. A systematic study of the spatial and temporal behavior of
the emissions, spanning different spatial and dynamic scales, is already in demand
from members of the space and planetary community. The HST dataset is also special
since it has spanned the whole Galileo orbiter mission. We request funding for a
systematic analysis and classification and other studies of the aurora with HST
imaging dataset. We will set up a portable scenario for comparative studies of
Galileo magnetic fields and particles data with HST iobservations. We will also
begin to compare the imaging results with global models of the magnetospheric
interactions on Jupiter in parallel with identifying other relevant infomation from
Galileo. This will fully prepare us for the following year to carry out a full
comparative study during the rare opportunity of the Cassini flyby coordinated with
the Galileo mission.
