000003316 520__ $$aWe investigate the 3D structure of coronal streamers, observed by white-light coronagraphs (SOHO/LASCO and STEREO/COR2). 3D reconstruction of coronal structures is often ambiguous. Inverse reconstructions are difficult, so we design a forward model based on plausible assumptions about the 3D streamer structure taken from previous physical models (a plasma sheet centered around a current sheet). The streamer stalk is approximated by a plasma sheet, with electron density that is characterized by three functions describing the radial, transverse and face-on profiles respectively. We simultaneously fit the observational data from SOHO and STEREO vantage points using a Powell minimization algorithm. We present the first results with this model using simultaneous observations near quadrature configuration.
