Coronal mass ejections are eruptive events in which large amounts of solar mass arereleased into the interplanetary medium. If the CME travels to Earth, the plasma particles crossour magnetosphere and generate significant geomagnetic storms. These storms are capable ofcausing disruptions in global communication and navigation networks, or satellite failures orcommercial energy systems, so these types of events are of great interest.It is known that not all CMEs evolve radially and the deviations are mainly attributed to thedistribution of magnetic energy surrounding the coronal mass ejection formation area. For thisreason, to study the cases in which a deviation occurs, it is necessary to characterize the coronalenvironment during the first evolutionary stages of the ejection.In the present work, we show preliminary results of the numerical analysis of several simulatedmagnetic scenarios where a deviation of a CME can occur.
