Make similar observations of line_4: Saturn's disk center (excluding Rings and its shadow) and Northern aurora. FOC line_5: assist needed to locate aurora and set up on it. Make similar observations of line_6: Jupiter's equatorial region at LambdaIII (1965) = 100d and 280d and Jupiters's line_7: northern aurora near LambdaIII (1965) = 180d. The FOC will be needed to locate line_8: auroral "hot spot" and for HRS acquisition of it. Parallel observations using line_9: the HRS when another instrument is prime and looking at one of these planets or line_10: vicinity are needed to calibrate the background geocoronal Ly-alpha emission. line_11: These should duplicate the observing geometry for the planetary observations. line_12: Also make similar observations from 1456A to 1774A. line_15: PRIORITY = 1. CYCLE >=1 (ANY CYCLE) line_17: Lines 32-36 Cycle 0, Priority 2. ! question: 4 section: 1 line_1: 1100 - 1360A required line_2: spatial resolution required ! question: 5 section: 1 line_1: FOC image at Ly-alpha needed to locate auroral emission on Jupiter and Saturn line_2: and to point HRS to it. line_3: Obs. between quad. and opp. needed to min. geocoranal background emission line_4: (dark time). line_5: Certain central meridian longitudes of Jupiter and Saturn are needed. line_6: Tracking of auroral features need (planetary rotation). line_7: Geocoronal calibrations should match Sun-Earth-Planet observing geometry as line_8: much as possible (dayglow not equal to night emission) line_9: [automatic if observation is made close in time to planet observtion]. ! question: 6 section: 1 line_1: see (5) for geocoronal- calibration parallel observations and dark-time line_2: requirements. The geocorona is bright and superposes the planetary Ly-alpha line_3: emissions at low spectral resolution. It needs to be known in order to subtract line_4: it. It is dimmer at night and so dark time observations have weaker geocoronal line_5: contamination; better accuracy is achieved. It varies with Sun-Earth-Planet line_6: angle so each planet observations requires a geocoronal spectrum. line_7: Max. Doppler shift of geocorona occurs at quadrature. ! question: 7 section: 1 line_1: Initial reductions at STScI; line_2: Final reductions and analysis at Univ. Texas at Austin using our VAX 11/780 and line_3: Dual Cyber 170/750. line_4: Possible collaborative reductions by FOC team. ! question: 8 section: 1 line_1: Request geocoronal calibrations to be parallel-mode observations at no charge line_2: when another instrument is prime and looking at planets [or a big vicinity line_3: (~10d) around a planet we observed] within a month of my planet observation. line_5: Need FOC to acquire and locate emissions in auroral regions of Jupiter and line_6: Saturn. ! question: 10 section: 1 line_1: Cluster of VAX 11/780's and 6410. line_2: Dual cyber 170/750 (until Feb 1991) ! question: 13 section: 1 line_1: A low and medium resolution Ly-alpha and H2 emission survey for Jupiter, Saturn line_2: Titan, Uranus and Neptune, will be attempted using the HRS for comparative line_3: auroral studies. ! !end of general form text general_form_address: lname: TRAFTON fname: LAURENCE mi: M. category: PI inst: UNIVERSITY OF TEXAS addr_1: ASTRONOMY DEPT. addr_2: RLM 16.326 city: AUSTIN state: TX zip: 78712 country: USA phone: (512) 471-1476 ! ! end of general_form_address records !
