We present in this poster the electron density characterisation of a streamer observed by LASCO under 2 different angles of view. At the end of January 2004, due to a favorable configuration of the Solar corona, we are able to observe a streamer, first, from the side, and then, 7 days later, from the face. Using electron density inversion technics we have determined the density profiles characterising the lenght and the thickness of the streamer. Those density profiles were then used to refine a 3D model of a streamer that is compared to LASCO observations using ray tracing technics.
