WAVES spacecraft. The radio event appeared to be associated with the complex interaction of two coronal mass
ejections (CMEs) successively launched (February 14 and February 15) from the same active region.
Although the CME-CME interaction was widely studied (e.g. Temmer et al., 2014, Maricic et al., 2014, Mishra &
Srivastava, 2014) none of the analyses confirmed an association with the continuum-like radio emission.
The usual method of establishing temporal coincidence of radio continuum and a CME-CME interaction is not
applicable in this event due to a complex and long-lasting interaction of the CMEs. Therefore, we performed radio
triangulation studies (see also Magdalenic et al., 2014) which provided us with the 3D source positions of the
radio emission.
Comparison of the positions of radio sources and the reconstructed positions of the interacting CMEs, shows that
the source position of the continuum-like radio emission is about 0.5 AU away from the interacting CMEs. We can
therefore concluded that, in this event, the continuum-like emission is not the radio signature of the CME-CME
interaction.Workplace Institute of Atmospheric Physics Contact Kateřina Adamovičová, adamovicova@ufa.cas.cz, Tel.: 272 016 012 ; Kateřina Potužníková, kaca@ufa.cas.cz, Tel.: 272 016 019 Year of Publishing 2018
