abstract:

    line_1:        After a blind-pointing maneuvre, to a point near the center
    line_2:        of Jupiter, but offset 0.67 arc sec south along the central
    line_3:        meridian, a series of FOS and GHRS spectra, covering the
    line_4:        range from approximately 160 to 330 nm, will be obtained.
    line_5:        The latitude chosen,  2 deg South, is as zonally uniform as
    line_6:        possible.   The planet will rotate under the HST aperture
    line_7:        about once as the spectra are being acquired. The resultant
    line_8:        spectrum will represent the zonal average spectrum at that
    line_9:        latitude, at nearly unit local air mass.  The spectrum will
    line_10:       be analyzed for compositional and vertical information,
    line_11:       using such species as NH3 and C2H2.   A single FOS exposure
    line_12:       will also be made, at high air mass, at the same latitude.

  question:        3
    section:       0
    line_1:        The acquisition will be by blind pointing near the center
    line_2:        of Jupiter.   The target is actually 0.67 arc sec south of
    line_3:        the center, along the central meridian.  The position angle
    line_4:        specified in the target list, level 2, includes the polar
    line_5:        position angle, 23.74 deg east of north, plus 180 deg to
    line_6:        obtain a southward offset along the central meridian.  The
    line_7:        size of the offset, 2 deg S lat, is chosen to point the HST
    line_8:        at the most nearly zonally uniform latitude near Jupiter's
    line_9:        equator.  Planetary motion and parallax will be tracked
    line_10:       during the spectroscopic exposures, but there will be no
    line_11:       tracking of planetary rotation.  The spectra will be taken
    line_12:       over approximately one Jovian rotation period, including
    line_13:       Earth-occultation and overhead time.  FOS spectra (2
    line_14:       gratings, 2 apertures each) and GHRS spectra (G200M, one
    line_15:       aperture, various positions) will obtain a zonally averaged
    line_16:       spectrum of Jupiter from 160 to 330 nm, at nearly zero
    line_17:       local air mass.  One additional FOS spectrum will observe
    line_18:       at the same latitude, at high local air mass.

  question:        4
    section:       0
    line_1:        The HST is required for access to the ultraviolet.  IUE
    line_2:        data are insufficient to obtain the desired spectral
    line_3:        information.

!

  question:        5
    section:       0
    line_1:        IUE spectra provide good estimates of exposure times.

!

  question:        6
    section:       0
    line_1:        If this program cannot be scheduled in mid-May, 1992, then
    line_2:        it may be necessary to update some of the pointng parameters
    line_3:        in the target list.

!

  question:        7
    section:       0
    line_1:        The HST spectra will be divided by published solar rocket
    line_2:        spectra to construct an albedo spectrum, which will be
    line_3:        analyzed for abundance and vertical distribution
    line_4:        information on various minor and trace species in the
    line_5:        atmosphere of Jupiter.
