Abstract
The determination of the propagation speed of Coronal Mass Ejections (CMEs) is usually done by tracking the motion of isolated brighter parcels of plasma embedded in the body of the eruption in coronagraphic and heliospheric imagers. In this work we explore the possibility to derive the 2D map of the instantaneous velocity distribution in the body of a CME. To this end, in this first test we analysed synthetic coronagraphic observations, to compare the derived CME speed with the expanding speed of the simulated eruption. First results are presented here.
