                         plasma and magnetic field that are expelled by the Sun into the 
                         heliosphere. CMEs pointing along the Sun-Earth line, called halo 
                         CMEs, are the main cause of geomagnetic storms. We select a set of 
                         31 halo CMEs from April of 2001 until December of 2015. We used a 
                         computational algorithm called CORonal Segmentation Technique 
                         (CORSET) to track the CME and calculate the kinematic parameters, 
                         such as radial and lateral expansion speeds. From the results of 
                         the 31 events we obtained an empirical relation between the radial 
                         and the lateral expansion speeds, described by the expression
