Solar disturbances modulate cosmic rays on different time scales. Studying cosmic ray variation is an important subject that attracts scientists from different disciplines. In this study, correlation analyses between cosmic ray muons and both the Solar Wind Velocity (V) and Sunspot Number (SSN) for the period between 2002-2010, have been conducted. Cosmic ray data were obtained from KACST muon detector, Riyadh, Saudi Arabia (24 43; 46 40; Rc =14.4 GV). We have found, that the cosmic ray muons are anti-correlated with both parameters. The same analyses have been carried out using data from Oulu Neutron monitor and comparable results with KACST detector have been found.
