The analysis of the November 6, 1997 event has taken advantage of the new capabilities of the OPorto Radiospectrograph and of the Nanccay Radioheliograph. The evolution of this event shows successive phases in time scales of a fraction of a second. It is shown that the CME observed by the LASCO/SOHO coronograph is the result of successive interactions of multiple loop systems which occur over a latitude range of about 100circ. These magnetic loop interactions lead to the creation of several electron acceleration sites which are widely separated in the corona. There is a close correspondance between the evolution of the CME seen by LASCO and the extend of radio sources seen by the radioheliograph. The association with particles detected by in situ measurements in the interplanetary medium is also presented.
