Hillaris, O. Malandraki, K.-L. Klein, P. Preka-Papadema, X. Moussas, C. Bouratzis, E. Mitsakou, P. Tsitsipis, A. Kontogeorgos] On 17 January 2005 two fast coronal mass ejections were recorded in close succession during two distinct episodes of a 3B/X3.8 flare. Both were accompanied by metre-to-kilometre type-III groups tracing energetic electrons that escape into the interplanetary space and by decametre-to-hectometre type-II bursts attributed to CME-driven shock waves. Apeculiar type-III burst group was observed below 600kHz 1.5 hours after the second type-III group. It occurred without any simultaneous activity at higher frequencies, around the time when the two CMEs were expected to interact. We associate this emission with the interaction of the CMEs at heliocentric distances of about 25R ⊙. Near-relativistic electrons observed by the EPAM experiment onboard ACE near 1AU revealed successive particle releases that can be associated with the two flare/CME events and the low-frequency type-III burst at the time of CME interaction. We compare the pros and cons of shock acceleration and acceleration in the course of magnetic reconnection for the escaping electron beams revealed by the type-III bursts and for the electrons measured insitu.
