Abstract : The launch of STEREO spacecraft with the capability of heliospheric imaging alongwith in-situ observations have provided us an opportunity to track and understand the propagation of CMEs from the Sun to the Earth and beyond. In this talk, I will present the results of a study of several cases of interaction of CMEs observed by STEREO/HI instruments. These CMEs were launched in quick succession and interacted as they propagated in the inner heiosphere. In particular, we investigate the nature of their collision /interaction and the dependence of the arrival time of these CMEs at the in-situ spacecraft, on the post-collision kinematics. The nature of collision and exchange of momentum for these cases of interacting CMEs will be presented. Further, we examine the signatures of collision and interaction of CMEs in in-situ observations. The consequences of interaction in strengthening the geoeffectiveness of CMEs is also looked into.
