abstract:

    line_1:        A set of observations of Jupiter with the GHRS Side 1, if available,
    line_2:        will be used to investigate the processes responsible for the
    line_3:        molecular hydrogen emission in the Jovian equatorial atmosphere.
    line_4:        The observations will span a complete Jovian rotation to determine
    line_5:        if there is a correlation with the "Lyman-alpha bulge". As they
    line_6:        will be made at a time close to solar minimum, it will be possible
    line_7:        to determine, by comparison with data from both Voyager and the
    line_8:        Hopkins Ultraviolet Telescope (at solar maximum), if these emissions
    line_9:        are controlled by the solar EUV flux as has been hypothesized.

  question:        3
    section:       1
    line_1:        A set of straightforward integrations with grating G140L of the
    line_2:        GHRS and the Large Science Aperture is requested.  Two long
    line_3:        exposures centered on the equatorial region of Jupiter will be
    line_4:        taken, one at the System III longitude of the Lyman-alpha bulge,
    line_5:        the other 180 degrees away.  In essence, the two exposures
    line_6:        will cover one complete rotation of the planet.
    line_7:        The other exposure will be taken of the Jovian north polar
    line_8:        aurora at 60 degrees north latitude and as close as possible to
    line_9:        System III longitude = 180 degrees.  Each observation will be made
    line_10:       at the same grating setting covering the wavelength range
    line_11:       1210 - 1490 A.

  question:        4
    section:       1
    line_1:        The electroglow problem has been studied extensively with Voyager
    line_2:        and IUE data sets but cannot be resolved with them because of the
    line_3:        poor spectral resolution of the former and poor detector efficiency
    line_4:        and contamination by long wavelength grating scattered light for
    line_5:        the latter.  The Hopkins Ultraviolet Telescope, which flew
    line_6:        on the Astro-1 space shuttle mission in December 1990, is well
    line_7:        suited to the problem but the reflight on Astro-2 is now
    line_8:        manifested for November 1994 at which time Jupiter is too
    line_9:        close to the sun to be observed.

  question:        5
    section:       1
    line_1:        The two long equatorial exposures must be centered at System III
    line_2:        longitudes of 90 and 270 degrees, respectively.  The north polar aurora
    line_3:        observation must be made at a time when the sub-Earth longitude of
    line_4:        Jupiter is 180 +/- 30 degrees.  This is to ensure that the LSA, placed
    line_5:        at 60 degrees N latitude, will include the auroral oval.  Dark time is
    line_6:        required to avoid contamination by terrestrial oxygen emission at 1304 A.

  question:        10
    section:       1
    line_1:        The Johns Hopkins University provides partial salary support of the
    line_2:        P.I., 80% of graduate student tuition fees, and contributes to the
    line_3:        maintenance of the computers and network facilities used in this program.
    line_4:        Similar support is provided by the other co-I institutions.
