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. ! ! end of abstract general_form_proposers: lname: FELDMAN fname: PAUL mi: D. inst: 2380 country: USA ! lname: HALL fname: DOYLE mi: T. inst: 2380 country: USA ! lname: MOOS fname: WARREN inst: 2380 country: USA ! lname: STROBEL fname: DARRELL mi: F. inst: 2380 country: USA ! lname: MCGRATH fname: MELISSA mi: A. inst: 3470 country: USA ! lname: BEN JAFFEL fname: LOTFI inst: 5436 country: FRANCE esa: Y ! lname: EMERICH fname: CLAUDE inst: 5448 country: FRANCE esa: Y ! ! end of general_form_proposers block general_form_text: 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: 6 section: 1 line_1: ! ! question: 8 section: 1 line_1: ! question: 9 section: 1 line_1: ID #2442: Cometary Parent Molecules, Feldman, PI (not related) line_2: ID #2481: HST Observations of Periodic Comets, Feldman, CoI (not related) line_3: ID #2483: The Volatile Composition of New Comets, Feldman, CoI (not related) line_4: ID #2625: Excitation Processes for the Outer Planet UV Emission, line_5: Moos, PI; McGrath, Strobel, CoIs (related) line_6: ID #2627: Io's Atmosphere and its Interaction with the Plasma Torus, line_7: Moos, PI; Feldman, McGrath, Strobel, CoIs (not related) line_8: ID #3064: HST Observations of Comet Levy (1990c),Feldman, CoI (not related) line_9: ID #3482: The Nature of the Variable Infalling Matter on the Star line_10: Beta Pictoris, Feldman, Moos, CoIs (not related) line_11: ID #3617: The UV Emissions of Titan, McGrath, PI; Feldman, Moos, line_12: Strobel, CoIs (not related) line_13: ID #3618: Excitation Processes for the Outer Planet UV Emission - Cycle 2 line_14: Continuation of #2625, Moos, PI; Feldman, McGrath, Strobel, CoIs (related) line_15: ID #3707: HST Observations of Periodic Comets, Feldman, CoI (not related) ! 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. ! !end of general form text general_form_address: lname: Feldman fname: Paul mi: D. category: PI inst: 2380 addr_1: Department of Physics and Astronomy city: Baltimore state: MD zip: 21218 country: USA phone: 410-516-7339 telex: pdf@pha.jhu.edu 410-516-5494 ! ! end of general_form_address records !
