Abstract FOC is the only imaging instrument able to resolve Jovian auroral features more accurately than 100 km (0.030 arcsec) and to locate them better than 200 km. This is needed to distinguish between the surface footprints of various thin adjacent layers in the outer magnetosphere (OM) where Ulysses and Voyager identified quite different plasma processes. We plan to monitor the aurorae when Galileo travels between 50 and 10-20 R_J on selected orbits where enough in-situ measurements allow to best characterize the state of the magnetosphere. This happens in orbits G2, C3 and C9 (01-06 september 1996, 01-07 november 1996, 22-31 june 1997). We will also try, as much as possible, to schedule the observations when the footprint of Io is visible on the dayside of Jupiter, in order to monitor its variation in various configurations, so as to provide constraints in the interpretation of the in-situ magnetic field and plasma data taken in the near vicinity of Io during the Io flyby. Complementary GHRS spectra dedicated to particle energy diagnostic at the footprint of Galileo, and emphasized in the TAC recommendations, are planned to be obtained with the repeat program 5440 for which the best observing conditions are first week of september 1996. Correlated analysis with the particle and field in-situ data by magnetic field mapping, a technique successfully used for Earth's magnetosphere studies, is guaranteed by the involvment of major Galileo Team Members. This opportunity, unique in our lifetime, will allow a comprehensive 3-D approach of the high latitude processes in the Jovian magnetosphere and magnify the scientific return of both Galileo and FOC. ------------------------------------------------------------------------------------ 6531( 9) - 07/31/96 17:34 - [ 2] Observations Description ------------------------ sectionObservations For each period of correlated observations, the program consists of a sequence of exposures allowing for a good view of the north and south auroral ovals. This allows to see the farside of the aurorae and thus to increase the window to periods when Galileo is in the pre-dawn or post-dusk sectors. Each HST orbit will provide two images, one of the north aurora and one of the south, except a few ones in which we will attempt imaging of one hemisphere at two different wavelengths for characterization of the energy of the precipitating particles. Quasi-simultaneous imaging of both hemispheres wil allow us to determind the planet limb quite accurately, and to reach the stringent requirement of absolute feature localization of the ~150 km or 0.05 arcsec, complementary to the high spatial resolution of ~100 km on auroral arcs (0.03 arcsec). This spatial scale corresponds to 0.2-1 RJ thickness layers in the outer magnetosphere sampled in about 0.5-2 hours by Galileo. We plan to use a sequence of four HST orbits in the first visit (01-06 september 1996) with the three last orbits centered near CML 65, 120, 180. The first orbit should be used for interactive acquisition because the apparent size of Jupiter is still large, and a 2 or 3 sigma error in the pointing could result in missing part of the auroral emissions expected. This orbit will however provide also one image with blind pointing. We plan to have these data just precede the observations of program 5440 (GHRS spectra followed by one series of FOC images) in order to realize a thorough monitoring of the auroral activity and characteristics during one of the Galileo orbits best studied by the particle and field instruments. The last four orbits will be split in two groups of two visits. Each group of visit consists of one orbit with CML near 35 and one orbit with CML near 170, taken during a single Jovian rotation period. One group of visit will be in the period 01-07 november 1996, and the other after 22 june 1997. The 14"x14" format will be used with 1024x512 zoomed pixels, and 8-bits words. Exposure times of about 15M with the combination of filters F152M/F175W will allow to obtain one good image of each hemisphere to monitor magnetic conjugacy effects, and short timescales variations. Similar exposure times used during previous programs just allows to fill an entire orbit when overheads are added. One or two orbits will consist of two images of the same hemisphere with the filters F152M/F175W, and 120M/140W which isolates shorter wavelengths. The ratio of the two images will provide a map of the particle penetration depth. This will provide information on the particle energy, less accurately than a spectrum, but with a global view of the auroral features. Exposure times will then be about 17 and 11 mn. sectionData Analysis and Team Expertise Our team involves investigators which cover all fields of expertise needed, - to optimize the observations, with the participation of major members of the Galileo particle-and-field Teams, L. Frank (PI of the energetic particle instrument), M. Kivelson and D. Southwood (PI and CoI of the magnetometer) , P. Louarn from IDS A. Roux's team, and of leaders of past HST programs (FOC and GHRS) R. Prange and L. Ben Jaffel, - to process and analyze the data (R. Prange, D. Rego , and L. Ben Jaffel have a strong experience with FOC images and GHRS spectra). Computer codes have been developed by D. Rego and L. Ben Jaffel to model the energy/species-dependent spectral signature of particle precipitations and the radiative transfer at Lyman Alpha. R. Prange and D. Rego have also developed the software needed for image processing and some specific codes (i.e. spatial filtering codes to increase the contrast of the features), R. Prange, M. Kivelson, L. Frank, D. Southwood, P. Zarka and P. Louarn have the necessary skills and experience to model and interpret the correlation with in- situ data, and the magnetospheric processes (R.Prange and D. Southwood initiated the FOC/Ulysses correlation study, R. Prange and P. Zarka have lead a fruitful comparison of Ulysses/IUE observations; R. Prange is also involved in correlated studies with the Ulysses's plasma, energetic particles and waves teams; L. Frank and P. Louarn have been heavily involved in similar studies on the Earth aurorae, with DE1, Viking, Freja)., The coordinated program of monitoring of the auroral activity is based on previous experience. Members of our team have already conducted successfully similar programs together in the past. R. Prange has a long experience with IUE/HST coordinated observations and is the European PI of the 19th year IUE program which has been allocated 812 hours of observing time as a "Key Project" (post SL9 and correlated observations with Galileo). S. Miller one of the four IRTF Science Team members for the campaign correlated with Galileo, and he has participated in correlated UV/IR auroral studies with R. Prange. P. Zarka is Head of the french radiodecameter array in Nancay and has been coI of several radio and wave instruments aboard deep space missions. He has already participated in studies of corrrelation of radio and UV auroral activity with R. Prange. Simultaneous observations will be executed with IUE in order to provide a temporal monitoring of the Jovian auroral activity in a period covering and overlapping the HST observations. DAM radio observations will also be performed simultaneously, in particular with the french Radio Array of Nancay, by P. Zarka. Simultaneous IR ground-base images in the IR H_3^+ emissions are scheduled by S. Miller at IRTF and UKIRT during the first week of september 1996. Real Time Justification ----------------------- During the first visit (01-06 september 1996) the apparent size of Jupiter is still large, and a 2 or 3 sigma error in the pointing (i.e. 2-3 arcsec), which may at times happen could result in missing part of the auroral emissions expected. We need therefore an Interactive Acquisition on the south auroral oval in the first orbit. However, if there were a more simple way to GUARANTEE an accuracy better than 1arcsec, we would accept it.

Since Jupiter does not move much (near stationary point) it may be possible to perform the acquisition about 11.5 to 6.5 hours before exposure 2 (either the north or the south auroral oval fully in view) - The interactive acquisition could be removed if, and only if, we could use a pair of guide star with particularly well determined coordinates so that the pointing accuracy could be GUARANTEED to be at least 1" - 3.
