A number of MHD instabilities are thought to be important in the eruption of solar prominences / filaments. Instabilities in prominence cavities can be categorized as flow-driven (plasma dominated) and field-driven (magnetic field dominated). Despite significant progress in observational analysis of prominence plasma very little is known about its magnetic nature. Here we use height-time plots to track the leading edge of the 27th Feb 2013 prominence eruption, via radial slits, using coordinated SDO/AIA and NoRH observations. From the derivatives of the height-time properties we deduce kinematic properties such as velocity and acceleration profiles. The kinematics are analysed to investigate important new correlations between the kink and torus instabilities and their role in prominence eruptions.
