             abstract = "Coronal mass ejections are the main source of space weather 
                         disturbances, thus understanding their evolution is a crussial 
                         point for forecasting their impacts at earth. Near the sun, 3 
                         dimentional observations are not available, thus the 3D geometry 
                         of CMEs are still under debate. Based on 2D observational 
                         parameters we investigate the possible 3D geometry of coronal mass 
                         ejections. These parameters are the perpendicular expansion and 
                         the radial expansion. Three cone models are annalized and their 
                         evolution studied. If the geometry of CMEs is known, and if it is 
                         possible to have a similar model for all CMEs, this can be used to 
                         correct and interpret the meaning of the plane-of-sky speeds 
                         measured by coronagraphs like the Large Angle and Spectroscopic 
                         Coronagraph - LASCO, abord the Solar and Heliospheric Observatory 
                         - SOHO. This knowledge would improve subtancially the forecasting 
                         of CME arrival time at earth models.",
