Summary

Using the data recorded at the Budkov Observatory in the years 1965–71, the following characteristics of earth current Pc1 pulsations were determined: period, amplitude and overall period of duration. Their diurnal and annual variations, their dependence on the solar cycle and on the general magnetic activity are studied. The cross-correlation of these characteristics and their association with the critical frequencies f0F2 and f0Es of ionospheric layers and with the solar radio flux on frequencies of 3750 and 9400 MHz are investigated. The results are presented in graphical form.
