Solar minimum streamer densities and temperatures using Whole Sun Month coordinated data sets

We model electron densities of the simplest, most symmetric solar minimum s treamer structure observed during the Whole Sun Month (WSM) campaign, using coronal observations of both visible white light and extreme ultraviolet ( EUV) emission. Using white light data from the SOHO/LASCO/C2 and HAO/ Mauna Loa Mark 3 coronagraphs, we determine electron densities by way of a Van d e Hulst inversion. We compare the white light densities to those determined from the density sensitive EUV line ratios of Si IX 350/342 Angstrom obser ved by the SOHO/coronal diagnostic spectrometer (CDS). Moreover, from the w hite light density profiles we calculate hydrostatic temperature profiles a nd compare to temperatures derived from the Si XII/Mg X line ratio. We find the white light and spectral analysis produce consistent density and tempe rature information.
