Long-term changes in Pc 1 pulsations and their dependence on latitude are analyzed using data recorded by five stations in Finland during the IMS. The daily Pc 1 occurrences at each station are plotted against the daytime f0F2 parameter. It is found that while the averaged daily durations of morning (Pc 1) pulsations generally decrease with increasing critical frequency (electron density) of the F2-layer, three somewhat different trends can be distinguished for the five stations. It is also found that the indirect connection between mid-latitude Pc 1 pulsations and increased ionospheric absorption of LF radio waves following certain geomagnetic storms (Marcz and Vero, 1977) holds in the case of high-latitude Pc 1 data.
