Abstract Our primary interest is the spectral profile of the Lyman alpha line at high and low spectral resolution, in several characteristic regions of the north Jovian aurora, together with the H2 Lyman and Werner spectrum important for its interpretation. The Lyman alpha line at high resolution, aimed to diagnose the auroral atmosphere ([H], T profile) and the precipitating particle properties (energy, species, superthermal proton outflows) will be obtained with the GHRS Echelle A, and LSA because of the low sensitivity . The search for extended red shifted Lyman alpha wing , typical of proton precipitation, will be performed at medium (subA) resolution with GHRS/SSA and low resolution with GHRS/LSA. The use of SSA insures the spectral and spatial resolution (arcs may be as narrow as 0.1"), but with a low count-rate. By contrast use of GHRS/LSA will provide a a reasonable count-rate at the expense of resolution. This will provide for free the H2 spectrum required to fully interpret the information in the Lyman alpha data through our models. The features investigated here are signatures of specific auroral processes, and they are not expected to be present in the whole auroral region. Consequently, we will target with particular care a few specific areas: (1) the narrow high latitude arc at longitudes both sides of 150 deg. (~120 and 200 on L~30) (2) the diffuse spot centered on 150-160 deg. In the spot extending north and south of L~30, the processes may be different in the polar and low latitude areas, so that spectra will be performed separately on both regions. Since the spectra must not be contaminated by signatures of different processes acting in nearby areas, and by contrast to any previous observations, PARTICULAR ATTENTION will be paid to the ACCURATE POSITIONING OF THE APERTURE. Although this was of course not in the initial proposal, the scientific return of these observations in terms of precipitating particle processes will be increased by orders of magnitude if they are coupled with our Cycle 6 program 6531, and scheduled while Galileo is taking in-situ particle and field measurements (this also provides just the conditions we had in Cycle 4 concerning the Doppler separation between the Earth geocorona and the Jovian Lyman alpha line which proved to be extremely favorable) ------------------------------------------------------------------------------------ 5440( 21) - 07/16/96 13:15 - [ 2] Observations Description ------------------------ SectionObservations We will target the CLM range 100-250 (three consecutive HST orbits) where the north aurora is visible from Earth during two consecutive rotations of Jupiter to take a series of Lyman alpha and H2 spectra (LSA) on the same set of four auroral features, and in exactly the same geometric conditions on the planet. A third rotation of Jupiter will be observed during only one or two HST orbits (due to time limitation) with SSA on a particularly bright feature, the narrow high latitude arc near longitude lambda III = 200 degrees. The control of the pointing accuracy and the precise location of the features of interest at the epoch of the observations is essential. The data obtained in Cycle 4 were of extremely good quality, showing for the first time the core reversal of the Lyman alpha profile in a planetary emission, but unexpected errors in the target pointing at some wavelengths, and the distance between the targets and the expected features make it difficult to interpret. Therefore, we will insure a pointing accuracy of about 0.1" by an Onboard acquisition using a Galilean satellite. It may perhaps be possible to perform only 1 such acquisition since the observations would be best scheduled in the week of the stationary point of Jupiter. Control of the precise location of the features (within 0.1-0.2" which is about the size of some of the features) at the time of the observations will be obtained from FOC images (F152M+F175W in the H2 Lyman band) taken one Jovian rotation later across the same CML ranges. We plan to take another set of images before the spectral observations using part of our Cycle 6 program (ID6531) to control of any time variability during the course of the observations. To minimize the risk of missing the narrow arc, the observations using SSA will be done with a fixed line of sight, letting the arc move below the slit, and be scanned "passively" through consecutive exposures, during the whole unocculted part of the orbit. One orbit is dedicated to a geocoronal background exposure with the Echelle-A. Our Cycle 4 data show that the best compromise between Doppler separation and geocoronal brightness is obtained about 2 months after opposition. The analysis of the Cycle 4 data also confirm that the wavelength calibration performed at Lyman alpha was extremely important, and WAVE spectra will again be taken. sectionData Analysis and Team Expertise The PI and most co-Is have a wide scientific experience in the field of planetary atmospheres and magnetospheres, and in data processing. The proposing team has an extensive experience in reducing IUE and HST spectra,` (especially at University of Michigan and IAP) and HST images (especially at IA Liege, IAS and IAP) as shown in the next question. Most coIs have experience with the STScI pipeline and support. Standard programs obtained from the STScI and/or developed at the coIs' institutions involve flat fielding, shifting and coadding the individuals FP- split segment, measuring and substracting the geocoronal background (spectra), retrieving precise pointing with limb fitting procedures, deconvolving aberrated data, rotating features on a planetary disc, etc (images). Once the data are reduced for the various geometrical configurations, they will be compared with models developed at the PI institution, IA Liege and IAP which generate synthetic Lyman alpha+H2 band profiles for different incident particles and energies, and different model atmospheres and which include the effect of radiative transfer. They will also be compared to previous profiles obtained at different locations by J. Clarke and during the Cycle 3 GO program in which several of the present coIs are involved. Finally, when the physical quantities will be derived from the data in the various auroral features investigated, they will be checked against various magnetospheric models to derive better understanding of the Jovian auroral Real Time Justification ----------------------- Calibration Justification ------------------------- WAVE calibrations are extremely important since asymmetric core reversals have been observed on the Lyman alpha line in Cycle 4. Careful wavelength calibrations have allowed us to attribute them in some cases to Doppler shifts of less than 10 mA of the line itself.

Observations to be correlated with Galileo particle and field measurements on orbit G2 within 50 RJ - 2-8 september 1996 - scheduling in the second part of the designated period if possible in order to allow scheduling of part of Cycle 6 program ID6531 prior to it - two orbits for FOC images formore complete sampling of Galileo path - 2. The Io acq must be done at the end of orbit 1, which must not be not filled by any science exposures - 3. The group of exposures 102-to-104, 105-to-107, and 108-to-110 must each fill a complete, separate orbit as they correspond to different CMLs on Jupiter, and 111-to-113 is a Lyman alpha sky background which is taken with exactly the same timing as the planet observations (very variable geo along orbit) - 4. The waves should be scheduled during the occultation time because the signal to noise is small already for the science observations in a single orbit - 5. REMARK Two Io acq could be saved if the SAVE/USE OFFSET can be used, by overriding the 3 days delay with an AFTER BY, during this period where Jupiter is quasi stationary (within a circle of 42" radius) 6. In this version, the Io acquisitions have been desactivated because I have not managed to force RPS2 to schedule it at the end of its orbit. Please, can you do this for me.

The group of exposures 202-to-204, 205- to-207, and 208-to-210 must each fill a complete, separate orbit as they correspond to different CMLs on Jupiter - 3. The waves at the beginning of the orbit should be scheduled during the occulted time because the signal to noise is small already for the science observations in a single orbit.
