The initiation of Coronal mass ejections (CMEs) is one of the major solar events that has not been fully modelled yet. The causal relationship between the sunspot groups and the CMEs can be uncovered by identifying the sunspot groups that are present at the base of the large scale magnetic loops that can distort or undergo magnetic reconnection which as a consequence result in CMEs. For this purpose, NASA’s SOHO mission’s Large Angle and Spectroscopic Coronagraph (LASCO) and magnetic doppler imager (MDI) along with Solar Dynamics Observatory’s (SDO) Helioseismic and Magnetic Imager (HMI) can be used to identify these sunspot groups with respect to their respective CMEs. The relationship between the parameters of these identified sunspot groups with respect to the CMEs reveals the causal relationship between these two solar phenomena. In this study we have identified these sunspot groups and related them to the CMEs with the help of a custom written code. Moreover, a machine learning technique using K-means for classification is being developed to find these causal relationships in the identified sunspot groups with their respective CMEs. This study in this manner can provide insight into the initiation of the CMEs.
