Abstract: | Short-period pulsations recorded at five stations in Finland during the IMS have been compared. The morning occurrences accepted as Pc 1's showed certain peculiarities in their dependence on latitude. A connection was found between the averaged daily duration of Pc 1's and the foF2 parameter. This hints at the influence of propagation conditions. It was found that, after certain geomagnetic storms, the mid-latitude ionospheric absorption of LF radio waves can significantly increase when the Pc 1 activity is also enhanced at each high-latitude station. |
