IMAGEing the Plasmasphere Phillip Webb NASA Goddard Space Flight Center NASA's Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) satellite was launched on March 25, 2000 into a 14 hour polar orbit that varies between a perigee altitude of ~1000 km and a ~7 RE apogee altitude. From this vantage-point the different science instruments on IMAGE are able to study the inner magnetosphere in ways that have never before been possible. This talk will give an overview of the different science instruments operating on IMAGE, and then focus on observations of the plasmasphere obtained from the EUV Imager and Radio Plasma Imager (RPI). Both these instruments have provided new and dramatic insights into the dynamics and structures of the plasmasphere. By viewing the resonant scattering of sunlight off He+ the EUV Imager can directly observe the global motion of the plasmasphere, something that has never before been possible. These observations have resulted in dramatic "movies" that clearly show the evolution of the plasmasphere during periods of varying geomagnetic activity, including storms. As the first long-range magnetospheric radio sounder, the RPI has returned observations of magnetospheric field-aligned echoes that have allowed, for the first time, plasmaspheric magnetic field-aligned electron density profiles to be obtained. Among its other achievements, the RPI has returned tantalizing observations of what may prove to be echoes from the magnetopause and also allowed the source of kilometric continuum radiation to be determined. _______________ Presentation - 12 November 2002, Department of Physics, La Trobe University, Melbourne, Australia
