Coronal restructuring and electron acceleration following a filament eruption

We present a multi wavelength observation of a filament eruption occurring on September 2nd 1999. The slow pre-event evolution of the filament ends wi th energy release signaled by a faint radio burst observed with the Nancay Radioheliograph and a faint LDE. The restructuring of a large area around t he site of the eruption was monitored both with SOHO/EIT observations as we ll as with the radio data. A moving noise storm occurred in the vicinity of the initial radio burst in coincidence with a faint coronal brightening ob served with the LASCO coronagraph; no Coronal Mass Ejection was seen. On a smaller energetic scale, this event presents several manifestations of coro nal disturbances observed in many CME associated events. Finally, it makes the link between previous studies on noise storm onsets and coronal restruc turing.
