- A summary is presented for research undertaken, physical insight gained, and new directives identified in this project. Significant enhancements for the SO2 neutral cloud model and its dissociative products (SO, O2, O, S) as well as its application to investigating the amount of SO2+ measured by the Voyager PLS instrument in the plasma torus inside of Io's orbit are discussed. New excitation rates for UV and visible emission lines were incorporated in the O and S neutral cloud models, and the very preliminary analysis of UV observations near Io acquired in 1992 by the Hubble Space telescope is discussed. Observations for O('D) 6300 A emission near Io, preliminary reduction of these observations, and an initial assessment of these observations are presented. The analysis of 1985 sodium eclipse and emission data for Io has been completed and is contained in a paper in the Appendix. A larger data set for 1987 sodium emission observations, which will provide a new base for more detailed future studies, is described. A preliminary discussion is also presented for the likely nature of neutral gas clouds for the outer three Galilean satellites.
