Scientific paper

Using images from the STEREO/EUVI A and B spacecraft and stereoscopic triangulation methods developed by Aschwanden et al for the reconstruction of the 3D geometry of curvi-linear structures in the solar corona, we determine three dimensional model reconstructions of several long-lived prominences as well as their topology - in particular the twist and number of helical turns. The derived geometries are analyzed together with photospheric magnetograms and potential field extrapolations (PFFS) and compared to various models for the magnetic confinement and support of prominence plasmas.
