Duration of wave disturbances generated by solar terminator in magneto-conjugate areas

We consider a possible explanation of long duration of travelling wave packets (TWPs) generated by solar terminator (ST). We suggest a hypothesis about consecutive detecting of MHD-nature disturbances, generated by ST in magneto-conjugate area first and in observation area next. Registration beginning time depends on latitude. In summer in Japan TWP registration starts with ST arriving in magneto-conjugate region — about 2–3 hours depending on latitude before ST arrives to the observation point. Dynamic spectra show clearly additive character of registered disturbances. ST appearance over the registration point accompanies amplitude increment on TWP frequencies in spectrum.
