Fig. 1.

Left: time derivatives of a section of flare 092 (see Table 1) observed by GOES/XRS. The top panel shows the 1–8 Å emission and the bottom panel the 0.5–4 Å emission. Right: corresponding power spectra, where the red solid lines are broken power-law fits to the spectra, the red dotted lines represent the 95% confidence levels, and the red dashed lines the 99% levels. There is a significant peak in both power spectra at a period of .
