Diurnal very low frequency (VLF) sub‐ionospheric radiowave phase measurements show a night‐to‐day transition pattern. During this sunrise transition a phase perturbation, which consist of a phase overshoot followed by a small phase recovery to normal daytime values, is often observed. The variabilit...
