These line_4: images will be made with the second generation PC. These line_5: exposures will record the faint knots of ejecta in the light line_6: of H alpha and N II emission lines. They will tie into line_7: similar images made during cycles 0 and 3 using the PC I, and line_8: will establish the new baseline with PC II for studies of the line_9: proper motions of the ejecta over the next few years. ! ! end of abstract general_form_proposers: lname: EBBETS fname: DENNIS inst: BALL AEROSPACE CORPORATION country: USA ! lname: MALUMUTH fname: ELIOT inst: COMPUTER SCIENCES CORPORATION country: USA ! lname: WALBORN fname: NOLAN inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA ! lname: DAVIDSON fname: KRIS inst: UNIV OF MINNESOTA country: USA ! lname: WHITE fname: RICK inst: SPACE TELESCOPE SCIENCE INSTITUTE country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: The bright core of Eta Car will be positioned in one corner line_2: of the PC CCD. Exposures will be made with the line_3: narrow filter F658N to record the knots with minimal line_4: contamination from the Homunculus, and one shorter exposure line_5: with F675W to record fainter astrometric reference stars. line_6: This sequence will be repeated with Eta Car positioned in line_7: each of the four corners, to record the largest field of line_8: view surrounding the star with the resolution of the PC. ! question: 4 section: 1 line_1: Spatial resolution needed to study small line_2: scale structures in Homunculus, and to measure displacements line_3: and proper motions of outwardly moving ejecta. ! question: 5 section: 1 line_1: ! question: 7 section: 1 line_1: line_4: The stars visible on the line_5: wider filter frames will be used to establish the astrometric line_6: reference grid. The objective is to extend our cycle 3 line_7: baseline for long term monitoring of the proper motions of line_8: the ejecta. Other objectives are to characterize the number and line_9: size distribution of the individual knots, and to search for line_10: fainter and more distant ejecta. ! question: 9 section: 1 line_1: An early set of WFC and PC images were obtained in cycle 0 line_2: as part of GTO proposal 1186. Our preliminary analyses were line_3: described in the proceedings of the STScI workshop on mass loss, line_4: and in a poster paper at the Atlanta AAS meeting in January, line_5: 1992. Further results on the motions of the North Condensation line_6: were presented at the Madison ASP conference in June, 1992, line_7: and at the HST workshop in Sardinia in July, 1992. ! question: 10 section: 1 line_1: Travel support, computer facilities, publication expenses ! !end of general form text general_form_address: lname: EBBETS fname: DENNIS title: DR. category: PI inst: BALL AEROSPACE SYSTEMS GROUP addr_1: HRS PROJECT AR-1 addr_2: P.O.
