| Abstract: | The properties of specific high-latitude pulsations (ipcl) reveal the existence of a significant diurnal variation in latitude of the position of the day side cusp (Δφ  6°). This systematic change of the position of the cusp during 24 hr must be taken into account when the rapid shirtings of the cusp connected with the changes of magnetic activity are studied.A method of determination of the position of the cusp, using a limited number of ground stations is suggested. |
