Sažetak
We present a detailed study of the interaction process of two coronal mass ejections (CMEs) successively launched on 2011 February 14 (CME1) and 2011 February 15 (CME2). Reconstructing the three-dimensional shape and evolution of the flux ropes, we verify that the two CMEs interact. The frontal structure of both CMEs, measured along different position angles (PAs) over the entire latitudinal extent, reveals differences in the kinematics for the interacting flanks and the apexes. The interaction process is strongly PA-dependent in terms of timing as well as kinematical evolution. The central interaction occurs along PA-100◦, which shows the strongest changes in kinematics. During interaction, CME1 accelerates from ∼400 km s−1 to ∼700 km s−1 and CME2 decelerates from ∼1300 km s−1 to ∼600 km s−1. Our results indicate that a simplified scenario such as inelastic collision may not be sufficient to describe the CME–CME interaction. The magnetic field structures of the intertwining flux ropes and the momentum transfer due to shocks each play an important role in the interaction process.
