Profiles for time interval (bounded by vertical dashed lines) for which the cross-correlation coefficient between meter and microwave emission reaches 0.72. (a) Flux at 6 GHz (normalized, red curve) and time dependence of the meter flux, integrated over the frequency range 71 ± 0.5 MHz (black solid line). Before 05:45:15 the SRH correlation (blue curve) is shown. (b) Same, but for the meter flux, integrated over frequency range 53−80 MHz (black solid line). The 1 min smoothing window is used. (c) 1−8 Å GOES channel (solid curve), smoothing with 10 s window. (d) 304 Å profile (red solid line) and 171 Å profile (blue solid line) of the emissions summed over the pink frame and over the green frame (dash-dotted and dashed lines) in Fig. 5b.
