Seminar Abstract:

The density and flow direction of plasmas in magnetospheric tails provide important clues to the tail structure and dynamics.  The study of McAndrews et al. [Plasma in Saturn’s nightside magnetosphere and the implications for global circulation, Plan. Sp. Sci. (2009)] examined the properties of magnetospheric plasma primarily in the pre-dawn equatorial region of Saturn’s middle magnetosphere and tail.  Using subsequent data from Cassini’s continuing mission at Saturn, we update and extend this study.  We address near-equatorial Cassini/CAPS plasma observations between mid-2007 and mid-2011.  We focus on intervals when CAPS was able to view both inward and outward plasma flows, and we examine the spatial distribution and other properties of such flows.
