AB: Using Cassini magnetometer observations and modelling results we report on the state of the Kronian magnetosphere during the targeted Cassini Titan encounter (TA). The flyby is in the morning sector at 10h36m SLT and since Titan's orbital radius is close to the nominal magnetopause stand off distance, the encounter may occur in the magnetosphere, magnetosheath or solar wind. We will distinguish between these scenarios and discuss bow shock and magnetopause crossings, and the state of magnetospheric current systems. We will also compare the observed magnetic fields with model fields - essential for extracting satellite-magnetosphere interactions from the background magnetospheric field. For solar wind and magnetosheath encounters we will report on the structure of the IMF and the proximity of the encounter to Saturn's magnetosphere.
