A determination of the D/H ratio line_4: may result if the signal to noise is high enough. ! ! 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 foot of the Io flux tube is "visible" (i.e. Io line_3: orbital phase angle between 135degrees - 225degrees) and central meridian is line_4: lambdaIII (1965) = 160degrees - 220degrees. Point HRS aperture to brightest line_5: location and track it (Jupiter is rotating) for exposure. 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_11: Obtain geocoronal calibration observation line_12: with similar geocoronal - Sun - planet geometry, in parallel mode. ! 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 to reduce background Ly-alpha emission from geocorona. line_3: Geocoronal spectrum needed to remove blended Ly-alpha background emission. line_5: FOC image needed for locating auroral hot spots. ! question: 7 section: 1 line_1: Preliminary reductions of STScI line_3: Final reductions and analysis at U. TX using VAX 11/780 cluster ! question: 8 section: 1 line_1: Request geocoronal observations to be parallel at no charge ! question: 10 section: 1 line_1: VAX 11/780 line_2: Sun Sparcstation line_3: R.A.'s ! question: 13 section: 1 line_1: We will use the intermediate/high resolution modes of HRS to measure the line_2: LY-alpha profile for the strong Jovian auroral emission from H2, H and D. ! !end of general form text general_form_address: lname: TRAFTON fname: LAURENCE mi: M. category: PI inst: UNIVERSITY OF TEXAS AT AUSTIN addr_1: RLM 16.326 city: AUSTIN state: TX zip: 78712 country: USA phone: (512)471-1476 ! ! end of general_form_address records !
