Abstract: Coronal Mass Ejections (CMEs) are eruptions of solar plasma from the surface of the Sun that often exhibit a three-part structure: a bright leading front, a dark cavity, and a compact bright core. In this study, we perform a multi-wavelength analysis of a CME using white-light observations from K-Cor and extreme ultraviolet (EUV) observations from GOES-SUVI, which provides an extended field of view (up to ~1.8 solar radii). The data used is for the date 26th October, 2022. While white-light data reveal density structures, EUV imaging enables temperature diagnostics across different plasma regimes. By correlating CME features observed in white light with their EUV counterparts, we aim to identify the thermal characteristics of the structures seen in density alone. This approach provides insights into the long-debated question of whether CME cores represent hot or cool plasma. The methodology developed here is extendable to upcoming missions such as PROBA-3 (white light + Fe XIV) and SUIT (Mg II channel for cool plasma), offering a framework for future multi-wavelength CME studies.
