Free format text (please update) We propose to image the Saturn ultraviolet aurora and dark polar caps for a detailed investigation of the morphology of Saturn's aurora near both poles and a study of its relationship with the stratospheric polar haze possibly generated by auroral ionization. The purpose of these observations is manyfold : (1) To study the latitudinal, longitudinal and temporal variation of the aurora of both hemispheres. This result may be achieved by imaging a full planetary rotation using the UV sensitive Wood's filters of the WFPC2 camera. (2) To image polar caps in wavelengths without auroral contamination to obtain a multispectral high resolution mapping of the polar haze opacity and scattering properties Questions ! Free format text (please update) Observing_Description: We propose to first obtain a series of exposures of Saturn's disk with WFPC2 using the PC chip. Its field of view is wide enough to include both polar regions near opposition (where Saturn's apparent diameter is ~ 19 arcsec). For auroral and haze imaging, we plan to cover a full Saturnian rotation to image all planetary longitudes (8 HST orbits). In this way, we will determine if the auroral morphology and brightness exhibit a true longitudinal variation, fixed in SIII coordinates, as the Jovian aurora or is linked to local time as in the case of the Earth's aurora. The F160BW Wood's filter is ideally suited for the auroral mapping as it includes most of the H_2 Lyman and Werner bands and Ly-Alpha. This filter has a high red leak rejection and provides good contrast against the background sunlit planetary disk. Based on the typical peak brightness of ~ 150 kR previously observed with the FOC on Saturn's aurora on past experience with WFPC2 images of Jupiter's UV aurora, (Clarke J.T., et al., Science, 1995, 267, 1302) exposures ~ 1000s will provide a good compromise between auroral temporal variation, S/N ratio, smearing of the planetary rotation and cosmic noise background. Since temporal variations on the time scale of tens of minutes are expected, we take two consecutive 1000s exposures (no CR-SPLIT) with the same filter on alternate (odd numbered) HST orbits. If the aurora is steady over the ~ 50 min time span of Saturn visibility, the exposures will be co-added after suitable longitudinal shift. The two auroral F160BW exposures will be followed by a 10s exposure of the disk in the methane filter at 8929 Angstrom (FQCH4P15). This image will provide the accurate location of the planetary disk which is necessary for the detailed mapping of the aurora. Previous experience with the WFPC2 images obtained during the SL/9-Jupiter encounter has indicated that a WFPC2 1-pixel precision on the limb position may be obtained. This image will also be used to examine the polar haze morphology as it is known from Jupiter studies that high-altitude aerosols, because of their efficient scattering, are contrasted extremely well in the 8900 Angstrom \ methane band. , Even-numbered HST orbits will also start with a 1000s auroral image with the F160BW filter. A subsequent F160BW + F165LP 1500s exposure (no CR-SPLIT) will be made to separate the light reflected by the disk and absorbed by the polar hood aerosols from the auroral contribution. In this way, it will be possible to closely examine the morphology of the UV aerosols (without auroral contaminations) and compare the results with the methane band images which are sensitive to the same particles but at somewhat lower altitudes. , Finally, during the 9th orbit 1000s haze images with the F255W and F218W filters will be made. It will be useful as a calibration check of the F160BW + F165LP haze images since their stability and photometric responses are better characterized than that of the Wood's filter. In addition, the spectral response of F218W is quite similar to that of the F210M + F220W FOC filters used for previous studies. Real_Time_Justification: The observations should ideally be carried out near opposition. none Solar_System_Targets !
