Multi wavelength investigation of the eruption of a sigmoidal quiescent filament

We report the first observation of a filament eruption in the metric and decimetric range, where the behavior of the filament can be followed during the event via thermal radio emission diagnostics. The event, occurring on February 28th 2001, involved a quiescent filament in a sigmoid magnetic configuration, whose eruption is triggered by the birth of a small parasitic polarity. Faint radio bursts mark the beginning of the event, which shows the appearance of a brightness temperature depression associated with the filament seen in ei

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 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 soh
