The continuum-like emission patch has a particular morphology and might be considered either as a continuation of the decametric type II radio emission associated with the second CME, either as a continuation of the type III radio bursts associated with a flare from NOAA AR 11158. This ambiguity complicates the question on the possible origin of the continuum-like emission. In this work, we make us of a radio triangulation technique presented by Magdalenic et al., (2014) to obtain the 3D source positions of the continuum-like emission. Comparing the location of this radio emission, with the positions of the structures of the interacting CMEs, brings important information on the possible origin of the continuum-like emission.The first results indicate that the continuum-like radio emission might be a consequence of the interaction between the shock driven by the second CME and the streamer-like, post-eruption current sheet formed behind the first CME, as suggested by Temmer et al., (2014).
