A determination of the auroral D/H line_4: ratio will be attempted. ! ! end of abstract general_form_proposers: lname: TRAFTON fname: LAURENCE mi: M. inst: TEXAS, UNIVERSITY OF country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: Use FOC with Ly-alpha filter to locate brightest auroral emission in Jupiter's line_2: north polar region when the central meridian is line_4: lambdaIII (1965) = 100 - 180degrees. Point HRS aperture to brightest line_5: location and track it (Jupiter is rotating) for exposure. line_6: Use Map of Io to extract 1st order offset error for GS's line_8: Observe +/- 1 month of pre-opposition quadrature to maximize wavelength line_9: separation of H and D geocoronal and Jovian Ly-alpha emissions. line_10: Also observed late afternoon region of auroral arc for time line_11: of day effects. ! question: 4 section: 1 line_1: 1216A required line_2: spatial resolution required ! question: 5 section: 1 line_1: The auroral emission of Jupiter is spatially isolated at several areas near the line_2: poles but the precise location and extent are not known. It is believed that line_3: the foot of the Io flux tube may be a hot spot for auroral emission. We need to line_4: precisely locate the brightest emission using the FOC before observing it with line_5: the HRS. Need maximum short-wavelength Doppler separation from geocoronal line_6: Ly-alpha emission to minimize blending of H and D absorptions with line_7: geocoronal H emission. ! question: 6 section: 1 line_1: Darktime needed to reduce background Ly-alpha emission from geocorona. line_3: Separate geocoronal spectra are needed to remove blended Ly-alpha background line_5: emission. FOC image needed for locating the auroral hot spots. ! question: 7 section: 1 line_1: Preliminary reductions of STScI line_3: Final reductions and analysis at U.
