A
partial halo CME was observed by LASCO/SOHO and COR/STEREO-B
spacecraft on 26 April 2008. The event was observed as limb CME by
STEREO-A spacecraft. On-disk, UV signatures show EIT wave and
dimming, as well as post-eruptive arcades. The CME was detected
in-situ, three days after its eruption from the Sun. We apply
forward-modeling and polarization ratio techniques on this event in
order to derive its 3D structure, the true speed and the direction of
propagation. The travel time to the STEREO-B spacecraft is calculated
using the speed derived from the 3D reconstruction techniques.
Comparison of the calculated travel time with the real arrival time
is done in order to improve the reconstruction results. Analysis of
the source region will be also presented and discussed.
