Sažetak
Investigation of cosmic ray intensity through the period 1958-1975 showed that the solar cycle dependence is highly pronounced for the transient variations, less pronounced for the 27-day recurrent tendency and almost missed for the 13.5-day variation. Decreasing and increasing phases of solar activity are characterized by significant coherence of the geomagnetic KP-index with 27-day recurrent tendency in cosmic ray intensity.
