Tracing CME Initiation from the Low Corona to the Inner Heliosphere

Recent advances in space-based solar instrumentation, from missions such as Parker Solar Probe, Solar Orbiter, Proba3, Aditya, and PUNCH, have significantly expanded our ability to observe the solar corona across a wide range of wavelengths, spatial scales, and observational geometries. By combining EUV imaging with white-light coronagraphic and heliospheric observations, both static and dynamic coronal structures can now be investigated in unprecedented detail. Recent advances in coronal polarimetry provide new opportunities to probe the coronal magnetic field, offering additional constraints on the 3D geometry of coronal mass ejections (CMEs) and on the dynamics of the expanding corona. Special focus lies on the onset of CMEs, which can be tracked continuously from their low-coronal onset through the early stages of their outward propagation. This contribution highlights the synergy between these complementary observations, demonstrating how multi-passband and multi-vantage-point measurements provide new insights into CME initiation, further evolution, and coronal structuring.
