Miralles: Lead Scientist ---------- M. Uzzo: Planner, Commander Y.-K. Ko R. Wu Command file: 04.07.09.12:34:05.cmd.log Activity: --------- 1) Coordinated UVCS Observations and Faraday Rotation Measurements during the 2004 Cassini Solar Conjunction Sequence: 04.07_Cassini.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. We expect Cassini to pass behind a streamer on July 9 - 10 at heights ranging between 1.75 and 4 solar radii. UVCS will observe O VI and Lyman lines to determine kinetic temperatures, average densities and outflow speeds.
