Ludhiana - Punjab (INDIA ) <p style="text-align: justify;">In the present study, we investigate the relationship between Coronal Mass Ejection (CME) and Cosmic ray intensity (CRI) variation on long-term basis. In this work, we extend the effects of CMEs rates on cosmic rays for the solar cycle 23. To carry out the study, we take all Coronal Mass Ejection data of LASCO during the period of solar cycle 23. From the analysis, we observed a good relationship between occurrence rate of CMEs and cosmic ray intensity variation.</p> https://ultraphysicalsciences.org/paper/903/ A study of relation Coronal Mass
