Plasma properties from the multi-wavelength analysis of the November 1st 2003 CME/shock event

The analysis of the spectral properties and dynamic evolution of a cme/shock event observed on november 1st 2003 in white-light by the lasco coronagraph and in the ultraviolet by the uvcs instrument operating aboard soho, has been performed to compute the properties of some important plasma parameters in the middle corona below about 2r⊙. simultaneous observations obtained with the mlso/mk4 white-light coronagraph, providing both the early evolution of the cme expansion in the corona and the pre-shock electron density profile along the cme front, were also used to study this event. by combining the above information with the analysis of the metric type ii radio emission detected by ground-based radio spectrographs, we finally derive estimates of the values of the local alfven speed and magnetic field strength in the solar corona.
