Abstract This cycle 4 proposal is for far-UV imaging of Jupiter's north auroral emissions in the H Ly alpha (1216 A) and H2 Lyman and Werner bands (900-1650 A). We estimate that WFPC2 with the Na metal filter will have 4-5 times higher efficiency and a much larger dynamic range than the present FOC images of Jupiter's aurora. Auroral images with a limiting sensitivity a few kR are important to reveal the full structure of the FUV auroral emission region. The longitudinal and short-term temporal dependences of the brightest sector of the north aurora will also be observed. These observations will be performed as the Galileo spacecraft approaches Jupiter, with a record of the solar wind properties near Jupiter for comparison with the WFPC2 observed auroral brightness and L-shell footprint for identification of the excitation processes. These observations constitute the first phase on this WFPC2 GTO program on Jupiter's upper atmosphere. ------------------------------------------------------------------------------------ 8.

Description of proposed observations. One series of WF images covering 3 HST orbits (1/3 Jovian rotation) optimized for the brightest sector of the north aurora (near CML 180 deg) will be taken first, alternating the filter combinations: F160BW (detecting both H2 and H Ly a emissions), F160BW+F130LP (to separate the H Ly a component), and F160BW+F165LP (to separate the long-wavelength scattered light from Jupiter). Two short, red images with F673N using the same guide stars will register the limb position. To detect bright emissions, ~7-14 min exposures will be adequate. Exposures longer than 10 mins will be blurred E/W by Jupiter's rotation (~10 hr period), and the aurora may be varying on time scales as short as tens of seconds (by analogy to Earth). The above set of exposures will resolve the longitudinal and short term temporal dependences of the brightest emissions, dependent on the excitation processes. A second set of two long exposures with F160BW and F160BW+F130LP, followed by two shorter exposures with F160BW+F165LP and F673N, will be made of the north aurora active sector to resolve the full structure of the H and H2 emissions. These images may also show the equatorial airglow and Ly a 'bulge', and also limb brightening from optically thin H2 band emissions and from dayglow Ly a emission (due to scattering in the wings of the solar line by the increased slant column at the limb). The F160BW images will show the extent of the polar hood absorption and any structure possibly related to enhanced auroral photochemistry. Page 3 ------------------------------------------------------------------------------------ 4. Justification of need for HST observations. The far-UV emissions of Jupiter's aurora and airglow can only be recorded from a space-based platform due to atmospheric absorption. The UV emissions are important because they are directly excited by the precipitating energetic particles. While IR emissions imaged from the ground are important tracers of the ionospheric temperature (H3+) and thermal/abundance effects in the neutral atmosphere (CnHm), these may not reflect the direct excitation of the atmosphere. In addition, only the HST is capable of providing 0.1 arc sec resolution to image the UV emissions with high spatial resolution. The exposure strategy is outlined above. The UV images are timed for maximum sensitivity with a minimal amount of blurring E/W due to Jupiter's rotation. The longer exposures are timed for maximum sensitivity with a longitude-averaged view of the limb emissions. The F673N images are to register the position of the limb. The auroral emission image sequence is repeated due to the known auroral emission image sequence is repeated due to the known variability in Jupiter's aurora: each sequence is to determine the emission variability with Jovian rotation. In cycle 5, two sequences will determine longer-term variations. ------------------------------------------------------------------------------------ 5. Description of special scheduling requirements. The size of Jupiter is reduced significantly away from opposition, by about 4" within two months, and 8" within 3 months: The +/- 2 month window away from opposition is therefore desireable. These observations may be scheduled close in time (i.e. within a couple of orbits) with images of the Io torus emission (separate GTO proposal). We will try to arrange ground-based imaging of the H3+ and CnHm thermal emissions from Jupiter simultaneously (i.e. over the same Jovian rotation) with the WFPC2 images of the aurora. This will be important to determine the relation between the different emission processes, and we are particularly interested in establishing the relation between the spatial distribution of the directly-excited UV emissions and of the ionospheric H3+ emissions. We would also like to have simultaneous IUE observations in a sequence of spectra similar to the 14 year data base that exists from IUE. One of the important questions today is to understand how the FOC bright spots relate to the 180 deg. brightening at Jupiter's north pole observed repeatedly with IUE. ------------------------------------------------------------------------------------ 6. Description of special calibration exposures. Scheduling during dark time is required. We are imaging FUV emissions from H (Lyman alpha) and H2 (Lyman and Werner bands), some very weak emissions, and therefore require minimum contamination from geocoronal Ly a emission, to obtain the best possible S/N. The exposures cannot be interrupted because of Jupiter's fast rotation (10 hours) and temporal variations, and the exposures series have been planned accordingly. ------------------------------------------------------------------------------------ 8. Additional comments or special requests. NONE ------------------------------------------------------------------------------------ 9. Description of previous HST work. We estimate that WFPC2 with the Na metal filter will have 4-5 times higher efficiency and a much larger dynamic range than the present FOC images of Jupiter's aurora. ------------------------------------------------------------------------------------ 10. Resources to be supplied by investigator's institution(s). Unix workstations are available with IDL and the WFPC2 system SPICA software packages. Page 4 ------------------------------------------------------------------------------------ 13. This proposal constitutes the first step in our program to image Jupiter's FUV emissions arising from phenomena in the upper atmosphere/ionosphere of this planet. There are many unknowns about the characteristics of this atmospheric region and about the processes related to the magnetospheric and solar input, resulting in particular morphologies for the auroral and airglow emissions (eg, discrete vs diffuse aurora, the H Ly a bulge). The first steps are to concentrate on the brightest emissions from the north pole aurora, to fully identify the magnetospheric excitation processes at the time of the observations by accurately defining its variable structure down to its weaker emissions. Images for the weaker emissions may also show the equatorial airglow, the extent of the Ly a 'bulge'. We may also detect limb brightening from the optically thin H2 band emissions, and also from the dayglow Ly a emission due to scattering in the wings of the solar line by the increased slant column at the limb. From the cycle 4 data, a follow-up strategy will be identified for our future GTO observations, that will extend to the south aurora, of different characteristics than the north aurora, and of the poorly understood dayglow processes. ------------------------------------------------------------------------------------ 11.
