Description	Je prezentována analýza erupce z 20. srpna 2002 za použití pozorování družice RHESSI, H? a rádiové emise. V čase maxima rentg. emise rádiová data v decimetrickém frekvenčním rozsahu vykazovaly (relativistické) vzplanutí typu IIId . V tomto čase bylo naměřeno velmi ploché rentg. spektrum. Fitováním dvojité mocninné funkce v přiblížení modelu tlustého terče byl zjištěn nárůst hodnoty spodní energie elektronového spektra do hodnot až 81 keV. Tento vývoj spodní energie je interpretován jako možná mezera v energiích elektronů injektovaných do rentg. zdroje (model tlustého terče) a těch v okolním plazmatu. Na počátku H? erupce byly také zjištěny rychlé změny H? intensit nacházející se mimo rentg. zdroje. (cs) Analysis of the August 20, 2002 flare using RHESSI, H?, and radio observations is presented. Radio data in the decimetric frequency range showed the type IIId (relativistic) burst at the time of the X-ray maximum. At this time a very flat X-ray spectrum was measured. Fitted double power-law spectra in the thick-target model revealed an increase of the low energy cutoff in the electron spectrum that rose to as high as 81 keV. This cutoff evolution is interpreted as a possible gap in energies of electrons injected into the X-ray thick-target source and those of the background plasma. Fast changes of H? intensities were found to be located away from the X-ray sources in the beginning of the H? flare.
