Radio signature and Hα limb features of the 1979 March 9 and 1982 July 9 flares

Abstract
We present a comprehensive compilation of data for both events. Some typical Hα limb and type IV radio spectrogram features are found to be associated. The escape of matter out of loops visible in Hα via blob ejection or loop eruption is associated with fast drift burst signatures resp. early flare continuum (FCE) emission in radio spectra and pulses in HXR. The comparison of both events reveals that the metric radio‐HXR association is essentially a matter of particle escape conditions into the corona.
