Along their path, some CMEs can drive shock waves, which accelerate ions and electrons. These fast electrons can generate type II radio bursts at the local plasma frequency and/or its first harmonic. In this study we use data from the two STEREO spacecraft which carry both imaging and radio instruments with direction-finding capabilities allowing us to track energetic electrons responsible for radio bursts. We present an analysis of type II bursts observed on the November 29 – 30, 2013. The shock wave signatures were possibly generated by an interaction of two consecutive CMEs. We have investigated three time-frequency intervals when received radio waves were sufficiently intense for direction-finding analysis. The obtained positions of triangulated radio sources suggest that the CMEs propagate towards the STEREO-A. The IP shock associated with this event has been also observed in situ by the MESSENGER and STEREO-A spacecraft.
