	Activity:
	---------

	1) Faraday Rotation Measurements with Cassini Streamer Observation 

	Sequence: 05.07_Cassini_str4.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=288 degrees.

	OBS_PROG: Primary: Spatial Coverage
		  Sub Obj: Sensitivity

	SCI_OBJ:  Primary: Coronal Dynamics...Outflow Velocities
		  Sub Obj: Plasma Properties...Proton Temperature & Density

	OBJ:      Streamer

	CMP_NAME: Faraday Rotation Measurements, UVCS; Cassini (S/C); LASCO

	CMP_NUM:  7143

	Duration: start: 2005.07.25.03:57
