The Formation of Plasmaspheric Plumes and the Loss of Plasmaspheric Plasma to
the Boundary Layers

M. Spasojevic, D. L. Carpenter, U. S. Inan, B. R. Sandel,  and B. W. Reinisch


The IMAGE EUV instrument images the distribution of cold plasma in the
Earth's plasmasphere and inner magnetosphere. By tracking the location of the
plasmapause in sequences of EUV images, we will show detailed analysis of the
global response of the plasmasphere to a geomagnetic disturbance including
erosion of the plasmasphere and the formation of drainage plumes in the noon
to dusk quadrant. Also, by comparing the change in intensity in sequential
images, we will attempt to quantify the loss of plasma to the dayside
magnetopause.
