Dynamics of flare processes and variety of the fine structure of solar radio emission over a wide frequency range of 30 - 7000 MHz

Radiobursts exibiting fine structure observed over two years during the rising phase of Cycle 24 by the SBRS are analyzed. In five events zebra structure, various fiber bursts and fast pulsations were observed. Events on 15 and 24 February 2011 are of the greatest interest. The polarization of radio...

Summary:Radiobursts exibiting fine structure observed over two years during the rising phase of Cycle 24 by the SBRS are analyzed. In five events zebra structure, various fiber bursts and fast pulsations were observed. Events on 15 and 24 February 2011 are of the greatest interest. The polarization of radio emission in all three cases is related to the ordinary wave mode of radio emission.Almost all events in the microwave range contain superfine structure. It is possible that each type of fine structure is excited by the same mechanism, and the broad variety of events is related to the dynamics of flare processes.
