Abstract

We presented the Solar activity dependence of the solar-wind-effect on cosmic ray intensity variations at 30th ICRC. At that time, we showed the results obtained mainly by using the data of Kiel neutron monitor and Nagoya muon telescope. We now utilise the data of large GRAPES-3 tracking muon telescope collected during 9 years from 2000 to 2008. From the field of view of this telescope, we obtained the cosmic ray intensities corresponding to the median rigidity from 64.4 to 92.0 GV. We have investigated the rigidity dependence of the solar-wind-effect using this data together with the data of neutron monitors at Keil (17.2 GV) and at Mexico City (25.8 GV) for lower rigidity, and these are discussed in detail.
