Resumen:

Recent research has demonstrated the significant role played by magnetic structures surrounding coronal mass ejection (CME) events in their initial development and progression. Active regions, coronal holes, pseudostreamers, and helmet streamers are key components of the corona that contribute to the deviation of CME trajectories from their radial path. Therefore, comprehensive observational studies, coupled with theoretical interpretations and numerical simulations, are vital in understanding the early evolution of CMEs and accurately determining their three-dimensional trajectory in the interplanetary medium. This approach is crucial for reducing errors in estimating the arrival time of geoeffective events. In this concise review, we compile from the theoretical, numerical, and observational investigations that have provided insights into the factors influencing CME deflection away from their typical radial trajectory.
