Normalised time profiles of the flare emission in different spectral ranges. All the time profiles are normalised by their maxima. A colour of each curve within a panel corresponds to the colour of the legend in the panel. Panel a: Hα emission from the sources R1+R2, R1, R3, and R4. Panel b: X-ray flux observed by Fermi/GBM at 25–50 keV and KW at 20–80 keV, and derivative of the GOES flux, at 1–8 Å. Panel c: X-ray fluxes registered by Fermi/GBM 6–12 keV, by GOES at 1–8 Å, and by GOES at 0.5–4 Å. Panel d: microwave fluxes at 8 GHz, 5.7 GHz, and 4 GHz obtained with SSRS. Panel e: X-ray uncorrected fluxes registered by RHESSI at 6–12 keV, 12–25 keV, and 25–50 keV. The RHESSI sources shown in Fig. 2 were reconstructed within time intervals enclosed into pairs of the same-coloured vertical solid lines.
