Abstract
Solar activity modulates the cosmic ray (CR) particles with different magnitudes on different time scales. To better understand the modulation processes and characterize its influences on the observed CR flux, data from locations with different cutoff rigidities need to be investigated.
In this study, the impact of interplanetary magnetic field (IMF B), solar radio emission flux at 10.7 cm (F10.7), and Dst index on the cosmic rays measured by King Abdulaziz University (KAAU) muon detector was investigated and established. The KAAU located in Jeddah, western Saudi Arabia (Rc =14.8 GV) and being in operation since 2007.
The obtained results showed that the CR intensities are significantly correlated with the Dst index anti-correlated with the rest of the variables. The magnitude and strength of the correlations between the considered variables and CRs were determined and discussed. These results are in agreement with those obtained by several investigators.
