abstract:

    line_1:        After blind-pointing to the center of Jupiter, GHRS G160M spectra from
    line_2:        140 to 159 nm plus a single G200M setting at 178 nm, will be obtained.
    line_3:        Since the sub-Earth latitude is approximately -2.8 degrees during the
    line_4:        probable execution period (June 2, 1993), the observed region will be
    line_5:        nearly zonally uniform, free from recent (early March) activity in the
    line_6:        South Equatorial Belt and from stratospheric plumes to the north.  The
    line_7:        planet will rotate under the HST aperture as the spectra are acquired.
    line_8:        The resultant spectrum will represent the zonal average spectrum at that
    line_9:        latitude, at nearly unit local air mass.  The spectrum will be analyzed
    line_10:       for compositional information and vertical structure, using CO and C2H2
    line_11:       as probes.  At these wavelengths, NH3 will not be important.

  question:        3
    section:       1
    line_1:        The acquisition will be by blind pointing at the center of Jupiter
    line_2:        The actual target is therefore about -2.8 deg (South), which is the
    line_3:        sub-Earth latitude, where Jupiter is nearly zonally uniform. Recent
    line_4:        (March/93) activity in the SEB is to the south, and the well known
    line_5:        stratospheric plumes are northward.  Planetary motion and parallax
    line_6:        will be tracked during the spectroscopic exposures, but there will
    line_7:        be NO tracking of planetary rotation. Jupiter will rotate under the
    line_8:        the aperture as the data are taken.  The result will be a zonally-
    line_9:        averaged spectrum from 147 to 178 nm, at nearly unit local air mass.

  question:        4
    section:       1
    line_1:        The HST is required for access to the ultraviolet.  IUE data
    line_2:        are insufficient to obtain the desired spectral information.

!

  question:        5
    section:       1
    line_1:        IUE spectra provide good estimates of exposure times.

!

  question:        7
    section:       1
    line_1:        HST spectra will be divided by published solar rocket spectra,
    line_2:        to construct an albedo spectrum, which will be analyzed for
    line_3:        abundance and vertical distribution information on various
    line_4:        minor and trace species in the atmosphere of Jupiter.
