VLF amplitude perturbations for NLK and NWC measured at Suva, Fiji, as function of solar flare X-ray flux measured in dB relative to 1 µW/m2 in the 0.1–0.8 nm band, for low-solar activity conditions (red points and corresponding red best-fit curve) and moderate-solar activity conditions (blue points and corresponding blue best-fit curve)
