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. ! ! end of abstract general_form_proposers: lname: CALDWELL fname: JOHN mi: J. inst: YORK UNIVERSITY country: CANADA ! ! end of general_form_proposers block general_form_text: 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. ! !end of general form text general_form_address: lname: CALDWELL fname: JOHN mi: J. title: DR. category: PI inst: YORK UNIVERSITY addr_1: PHYSICS DEPARTMENT addr_2: 4700 KEELE ST city: NORTH YORK state: ON zip: M3J 1P3 country: CANADA ! ! end of general_form_address records !
