We present a multi wavelength observation of a filament eruption occurring on September 2nd 1999. The slow pre-event evolution of the filament ends with energy release signaled by a faint radio burst observed with the Nançay Radioheliograph and a faint LDE. The restructuring of a large area around the site of the eruption was monitored both with soho/eit observations as well 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 observed with the lasco coronagraph; no Coronal Mass Ejection was seen. On a smaller energetic scale, this event presents several manifestations of coronal disturbances observed in many CME associated events. Finally, it makes the link between previous studies on noise storm onsets and coronal restructuring.
