Scientific paper

We present observations of Coronal Mass Ejections (CMEs) in which we compare the trajectory of the CME with the events occurring at its origin. Two types of CME trajectories are observed. In some cases, the CME moves out radially above the associated flaring active region, in accordance with conventional wisdom and most current CME initiation models. In other instances, the CME appears deflected from this expected path. We find that the course of a deflected CME is influenced by the lateral motion of its associated dimming region low in the corona. We also observe two distinct sets of dynamics associated with dimming regions, and find that these dynamics correlate with the expected CME trajectory.
