AB: The Ion Neutral Camera on board Cassini has obtained Energetic Neutral Atom (ENA) images of the interaction between the energetic (10-200 keV) ions of the magnetosphere and Titan's outer exosphere. There are several Titan encounters where Titan's atmosphere is "illuminated" by the energetic ion clouds corotating over Titan. They are characterized by ENA emissions extending to large (10,000 km) altitudes above Titan. During periods when the energetic ion clouds are much larger than 10's of Titan radii, it is possible to investigate the distribution of Titan's outermost exosphere. We find that the images are consistent with an extended H₂ cloud extending out well beyond 10,000 km altitude with a 1/r² dependence.
