Context.Photospheric motions and a sheared configuration of the magnetic field are often considered as precursors of violent solar phenomena such as flares and Coronal Mass Ejections (CMEs). Therefore, in many numerical CME initiation studies shearing of the magnetic foot points is used as a mechanism to make the magnetic field unstable and to trigger the CME event.
