Scientific paper

We present a reconstruction of the energy transport scenario based on the simultaneous observations in a wide range of electromagnetic spectrum. Particularly, the high-temporal resolution optical and radio spectra from the Ondrejov observatory, data obtained by RHESSI, Nobeyama Radio Observatory, Radio Solar Telescope Network (RSTN), Siberian Solar Radio Telescope (SSRT) and SOHO (MDI and EIT) were analysed to obtain a complex view on the event. Especial attention was payed to the role of accelerated particles in the energy transport and to the excitation mechanisms in different kernels of the flare. As follows from the microwave data the maximum of emission at 17 GHz evolved from the eastern part of the flare to the western one. On chromospheric level the flare consisted of two eruptive centers - eastern and western ones. While the eastern center consisted from a single H? kernel, the western one was rather a complex structure. These centers were associated with different HXR sources. It is worth to note that the western center was connected with a more mighty HXR source of 25-100 keV.
We studied a correlation of the hard X-rays, radio emission and the Balmer series lines for the western center. Probable agents and scenarios of the energy transport as well as possible diagnostic aspects of the results are briefly discussed.
