| Abstract: Abstract
Solar activity produces Forbush effects as well as long-term modulations in galactic cosmic rays. This makes coronal mass ejections (CMEs), and flares, is the main sporadic manifestations of the solar activity, which should be considered in modulation on galactic cosmic rays. In this observation, a new version the CME-index is proposed based on a comparison of the data from coronographs with long-term variations of cosmic rays and Forbush effects. It is observed that the during minimum phase of Solar activity, the strength of the interplanetary magnetic field has been minimum, reduces the GCR entering inner- heliosphere and high anti-correlation with solar activity indices. It is also found that velocity of solar wind (Vsw) and turbulence and strength of the interplanetary magnetic field were positive correlated and, inverse correlated with count rate of cosmic ray intensity.
