The local and global patterns of plasmaspheric plasma transport reflect the influence of electric fields imposed
by all sources in the inner magnetosphere. Image sequences of thermal plasma distribution obtained from the
IMAGE Mission Extreme Ultraviolet Imager can be used to derive plasma motions and, using a magnetic field
model, the corresponding electric fields. These motions and fields directly reflect the dynamic coupling of injected
plasmasheet plasma and the ionosphere, in addition to solar wind and atmospheric drivers. What is being
learned about the morphology of inner magnetospheric electric fields during storm and quite conditions from this
new empirical tool will be presented and discussed.
