Time profiles of the radio flux at 3.79 GHz, the intensity enhancement R = I/I₀ at the Hα line center and 6562.8 ± 0.5 Å, the continuum contrast C = (I − I₀)/I at 4250 Å and 3600 Å, the RHESSI hard X-ray (50–100 keV) flux, and the GOES soft X-ray (1–8 Å) flux of the WLF. The light curves in the white-light and Hα bands are computed in the WLF kernel as shown in Fig. 1, and those in other bands are computed for the entire solar disk. The HXR data after 03:45 UT are omitted owing to a change of the various attenuators.
