Temporal variation of high-energy emissions. (a) GOES SXR flux of the 1.0–8.0 Å channel. (b) Time derivative of the GOES SXR flux. (c) NoRH 17 GHz microwave from the flare region. The preflare flux is subtracted. (d)–(e) Fermi/GBM HXR fluxes in the range of 29–31 keV and 50–100 keV. The horizontal axis is the elapsed time from the start time of the flare. The times of the seven snapshots in figure 4 are indicated by the arrows. The two-arrow line denotes the X (horizontal) range of figure 5 and figure 6. The observation time range of Hida DST is also shown.
