What Can UVCS Observations Tell Us about Coronal Mass Ejections
Abstract
The Ultraviolet Coronagraph Spectrometer (UVCS) on SOHO has observed a number of Coronal Mass Ejections at various heights and heliographic latitudes. We will focus on the changes in the physical conditions of the coronal plasma that can be observed with uv spectroscopic techniques. These changes may provide a clue to the origin of the material ejected by the CME. This work is supported in part by NASA under grant NAG-3192 to the Smithsonian Astrophysical Observatory, by the Italian Space Agency and by Swiss funding agencies.
