Image the south polar aurora line_3: on seven consecutive orbits, to cover one Jupiter rotation, near April 15, line_4: 1993. Starting time with respect to UT or to Jupiter's CML will be chosen line_5: to insure overlapping coverage near System III longitude 0 degrees at the line_6: beginning and end of the sequence. Continuum images will also be taken line_7: for limb-fitting. ! ! 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: 1 line_1: S/N estimate based on previous HST images, with FOC pixel binning to 2x2 line_2: (arcsec)^2 assumed. ! question: 5 section: 1 line_1: The Jupiter auroral observations should be executed near April 15, line_2: 1993, if possible. It is understood that the period of April 15, 1993, line_3: corresponds to an SAA avoidance period for the HST, and it is chosen line_4: to facilitate the consecutive orbit requirement. There will be a major line_5: attempt to have ground-based observers coordinate their observations line_6: with the HST observations in April, 1993, so if this requested time is line_7: not possible, for whatever reason, please inform the PI of the change line_8: as soon as possible (416-665-5449). ! question: 7 section: 1 line_1: Images will be calibrated and binned as necessary to produce optimum line_2: information. Exposures are limited not only by photons but also by planetary line_3: rotation, so that standard S/N estimates are not meaningful. Previous line_4: experience with HST/FOC images of the Jovian aurora shows that the chosen line_5: exposure times will produce excellent images. ! question: 13 section: 1 line_1: Auroral imaging of the polar regions of Jupiter will be performed with the line_2: FOC, using filters F175W and F152M in series, to reduce red leak and provide line_3: reasonable sensitivity to H2 emission at 1600 A. Continuum images at 2200A line_4: will also be obtained. Exposure times and the total number of line_7: exposures, being constrained by HST eficiency and orbital considerations and line_8: by Jupiter's rotation, cannot change. If the auroral images can be obtained line_9: without breaking guide-star lock, a second set of continuum images at the line_10: end of the auroral sequence may be omitted. line_12: Program updated 1/26/92 to include FOC bright object observing procedure. line_13: Dark exposures added, preceding each new filter combination. These should line_14: run during Earth occultation, but immediately before the associated science line_15: exposures. The visibility period following a DARK should start with a full line_16: guide star acq., to undo the effects of preceding SIPS. A pointed uplink line_17: should follow the guide star acq. If telemetry indicates the proper filters line_18: are in place, a precalculated SIP (based on the actual S/C roll angle) will line_19: be made and observations will continue. Contact Alex Storrs (SPB, x4903) line_20: for details. ! !end of general form text general_form_address: lname: CALDWELL fname: JOHN mi: J. title: DR. category: PI inst: YORK UNIVERSITY addr_1: PHYSICS DEPT addr_2: 4700 KEELE ST. city: NORTH YORK state: ON zip: M3J 1P3 country: CANADA ! ! end of general_form_address records !
