P. Miralles: Lead Scientist ---------- R. Wu: Commander M. Uzzo: Planner Command file: 05.07.25.16:00:00.cmd.log Activity: --------- 1) Faraday Rotation Measurements with Cassini CH OVI Observation Sequence: 05.07_Cassini_CH_OVI.tcl SCI_SPEC: The Cassini spacecraft will have a projected passage close to the solar limb. Recordings of Cassini's radio signal will be used to search for Faraday rotation fluctuations due to waves in the solar corona. UVCS will observe O VI and Lyman lines to determine kinetic temperatures, average densities and outflow speeds. Roll positions are VL-corrected for PA=358 degrees.
