At short wavelengths, the global line_4: reflectivity of Neptune is less than that of a pure Rayleigh atmosphere; thus line_5: structure may be visible. Observations will be made in four sequences, line_6: distributed over 18 hours. The tenuous ring system and the associated line_7: satellites will be observed with the Planetary Camera. ! ! end of abstract general_form_proposers: lname: WESTPHAL fname: JAMES mi: A. inst: CALTECH country: USA ! ! end of general_form_proposers block general_form_text: question: 2 section: 1 line_1: WF/PC observations will provide high-resolution images of Neptune and its rings line_2: in spectral regions not covered by Voyager imaging cameras and/or not possible line_3: from the Earth-based observations.
