Workshop; Seventh Solar Information Processing Workshop; 2014

In this work, we apply three widely used stereoscopic methods, namely the 'Forward modeling - FM', 'Tie-point reconstruction' and 'Polarization ratio technique - PR', in order to reconstruct the 3D structure of an erupting prominence and associated CME occurring on 16 April, 2012.The event was observed at the East limb from Earth and at the West limb from the STEREO B spacecraft, while it appeared as a back-sided halo CME in STEREO A images. We apply the different techniques to a sequence of images in order to study the propagation of the prominence and CME and determine both morphological and kinematics characteristics. To this end, we track the prominence in the low corona and the CME in the inner heliosphere combining both ground-based and space-borne data from STEREO, SDO and SOHO and MICA (Mirror Coronagraph for Argentina).
