  Abstract:  Our previous work on the theoretical αν model regarding transversal oscillations of coronal loops can be tested using a Matlab simulation. The simulation consists of a trajectory of the apex of the loop, with random elements, which mimics the observed pattern displayed by coronal oscillating loops. To this motion, a Kalman filter is applied and a connection between the Kalman filter parameters and the parameters of the αν model is discussed. Such a connection is not obvious at this point, but it is nonetheless clear that a Kalman filtering technique may be used in applications designed for real time prediction of coronal loop dynamics.

Keywords: Solar corona, transversal oscillations, Kalman filter
