Scientific paper

The Saturn Orbit Insertion (SOI) of Cassini took place on 1 July 2004. The Ion and Neutral Camera (INCA) obtained global energetic neutral atom (ENA) images of the magnetosphere during 1-2 July, while the LEMMS detector obtained in-situ ion and electron intensities and pitch-angle distributions. Since Cassini made a cut through the morning (inbound) and post-midnight (outbound) sector, we have enough information to use the INCA images and LEMMS in situ intensities to constrain the global ion distribution using simulations with a parametrized model adapted from Roelof and Skinner [2000]. The model for the neutral gas distribution was adapted from Richardson [1998]. From the ENA images, the ion distribution appeared to peak on the nightside, while the LEMMS ion and electron intensities displayed two strong peaks between 3 to 8 RS on both the inbound and outbound passes, with the outbound pass displaying stronger intensities. The LEMMS pitch-angle distributions exhibited clear depletions around 90 deg within these regions, consistent with ion/gas interactions contributing to the minima between the intensity peaks. Additional resolved ENA images and in situ intensities will be obtained after the first close Titan flyby (Ta) on 26 October 2004.
