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.
