Observe geocoronal Ly-alpha background line_4: emission separately. Search for emissions for line_5: aeronomical species generated by ion chemistry in the intense line_6: auroral emissions. ! ! end of abstract general_form_proposers: lname: TRAFTON fname: LAURENCE mi: M. inst: TEXAS, UNIVERSITY OF country: USA ! ! end of general_form_proposers block general_form_text: question: 3 section: 1 line_1: Observe Uranus at 1456 - 1774A and at 1072 - 1360A with the HRS line_2: low resolution mode of the HRS and large science aperture. ! question: 4 section: 1 line_1: FUV required line_2: spatial resolution required ! question: 5 section: 1 line_1: Dark time needed to minimize dayglow and geocoronal line_2: emissions. ! question: 6 section: 1 line_1: See (5) for geocoronal- calibration 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 for removal. line_4: Dark time observations encounter weaker geocoronal emissions line_5: and so produce truer planetary emission spectra. ! question: 7 section: 1 line_1: Initial reductions at STScI; line_2: Final reductions and analysis at Univ.
