We propose to observe line_7: occultations by these bodies with the ST, as the line_8: opportunites arise, to probe their atmospheres, line_9: determine their sizes and achieve other goals. With line_10: such diverse possibilities, one must examine each line_11: opportunity as it occurs and formulate an observing line_12: strategy to fit that particular case.

Each observation will require (i) a line_4: set of 2 onboard acquisitions; (ii) a scan of about line_5: twenty arc-seconds along the track that the object line_6: will follow relative to the occulting body and (iii) line_7: a time series run on the object with whatever filter line_8: aperture combination that is chosen for the line_9: observation. For some occultations to be observed in line_10: the far UV, prior multi-filter photometry of the line_11: object will be necessary in order to determine the line_12: most appropriate filter to use for the occultation. line_13: For now, we shall assume that the calibration and line_14: observation time will average about 30 minutes per line_15: occultation observed. ! question: 4 section: 1 line_1: We can achieve a much better signal-to-noise ratio line_2: for the temperature profiles and other information line_3: than can be obtained for small body occultations line_4: than has been possible from the ground for the line_5: following reasons: (i) the greatly improved line_6: photometric stability of ST photometry, which will line_7: substantially reduce the errors in the numerical line_8: inversion of the data that is necessary to obtain line_9: the temperature profiles; (ii) our ability to reject line_10: background light from the occulting object (such as line_11: a comet ) by employing small focal plane apertures; line_12: and (iii) the absence of scintillation noise, which line_13: has strong components at frequencies comparable to line_14: the occultation timescale. ! question: 5 section: 1 line_1: For resolved bodies with possible atmospheres, line_2: tracking the occulted star will require a real time line_3: update, due to its complicated path caused by line_4: refraction in the occulting body's atmosphere and line_5: the uncertainties in predicting the ST orbit. ! question: 6 section: 1 line_1: For comets and the larger bodies (Titan, Triton, and line_2: Pluto) a prior scan over 20 arc-seconds is needed to line_3: map the scattered light field, which is needed for line_4: the data reduction. ! question: 7 section: 1 line_1: Data will be reduced and analyzed at MIT with VAX line_2: 11-750 belonging to the planetary astronomy group. ! question: 10 section: 1 line_1: TBD ! question: 13 section: 1 line_1: An observation of an occultation by a comet, line_2: asteroid, satellite, or Pluto would yield a variety line_3: of information. For example, we could gain further line_4: information about the atmospheres of Pluto and line_5: Triton, including knowledge of the composition and line_6: structure of their atmospheres. Also, the presence line_7: of possible material in the neighborhood of an line_8: asteroid could be obtained. Opportunity stellar line_9: occultations by small bodies are proposed to be line_10: observed with the HSP or FOS. ! !end of general form text general_form_address: lname: BLESS fname: ROBERT mi: C. category: PI inst: UNIVERSITY OF WISCONSIN addr_1: DEPARTMENT OF ASTRONOMY addr_2: 475 NORTH CHARTER STREET city: MADISON state: WI zip: 53706 country: USA phone: 608-262-1715 ! ! end of general_form_address records fixed_targets: targnum: 10 name_1: TR18 name_2: STAR-191714-213001 descr_1: STAR TO BE OCCULTED BY TRITON. descr_2: CLOSE APPROACH AT 30-JUN-92:07:10 pos_1: RA = 19H 17M 13.456S +/- 0.2", pos_2: DEC = -21D 30' 01.04" +/- 0.2", equinox: J2000 acqpr_1: BKG comment_1: STAR POSITION WILL BE UPDATED comment_2: BEFORE OBSERVATION IS PERFORMED. comment_3: CONTACT: AMANDA S.
