Analysis of time structure of the radio and HXR-emission of solar flares produced by AR0069 and their connection with characteristics of SEP events
Abstract
The results of the experimental investigation of solar energetic particles acceleration and propagation based on the study of delays between radio and X-rays emission of flares produced by the active region 0069 in August 2002 are present. Parameters of SXR and HXR photon spectrum as characteristics of acceleration processes were compared with SEP flux, their maximal energy and spectral index. Structure analysis of delays between microwave, meter and X-ray emission was carried out in order to study processes of accelerated at the Sun particle propagation and possible mechanisms of additional acceleration. It was obtained that during this series of flares more powerful SEP events with higher energies were observed in time flares with the minimal delay between microwave and HXR emission. The obtained results are discussed in respect to possible models of the SEP propagation.
