Resumen:
We perform an analysis of the 3D structure and velocity of a CME
(coronal mass ejection) ejected on 2 January 2008. The event was imaged
by both STEREO A and B spacecraft (mutual separation of ?44°),
providing polarized images of the event from two different points of
view. To obtain information on the 3D structure of the CME from
polarized images, a polarization technique (Moran & Davila, Science
305, 66, 2003) is applied. Aided by this method, we have constructed
topographical maps which show the height of the various event features
from the plane of the sky (i.e. toward or away from the observer) and
have dinamically analyzed and compared the real and projected on the
plane of the sky velocities.
