Abstract : The Sun’s magnetic activity is drives changes in the near- Earth space environment, the heliosphere, and interplanetary medium. The structure of the heliosphere and produce changes in Galactic cosmic rays (GCRs) intensity controls by Solar variability. Solar variability occurs over a broad range of spatial and temporal scales. Inside the heliosphere Intensity of Galactic Cosmic Rays (GCRs) are affected by magnetic turbulence and solar wind disturbances. We performed the study of modulation in intensity of Galactic Cosmic Rays (GCRs) with phases of Solar Cycle minima in Sunspots. During maximum GCR intensity in the minimum phases of Solar Cycles with relation to main heliospheric parameters are determined, it is observed that GCR proton spectrum are their linear trends on heliospheric parameters in the minimum of solar cycles. It is high anti-correlation (-0.80) between Sunspot number (SSN) & GCR intensity in the minimum phases of Solar Cycle 23 / 24. It is observed that 10.7 cm Solar Radio Flux (SRF), Solar Wind Velocity (SWV) and the strength and turbulence of the interplanetary magnetic field (IMF) with count rate of cosmic ray intensity are inverse correlated.
