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 speed and sunspot number for the period between 2002 and 2012 have been conducted. Cosmic ray data were obtained from the KACST muon detector in Riyadh, Saudi Arabia (24 43; 46 40; Rc =14.4 GV). We have found that cosmic ray muons are anti-correlated with both parameters. The same analyses have been carried out using data from the Oulu neutron monitor and comparable results with the KACST detector have been found.
