Multi-view study of March 28 2022 CME observed by SoloHI

Although many CMEs (Coronal Mass Ejections) can be described in detail by identifying their shock, leading edge and cavity during their evolution throughout the heliosphere, a significant number of CMEs are distorted or merged with other structures, making interpretation of the observations more challenging. New solar missions provide observations from closer to the Sun that are crucial to identify CME structures with more definition from new viewpoints, and, thereby, enrich our global understanding of these events. The Solar Orbiter Heliospheric Imager (SoloHI) onboard the Solar Orbiter mission offers high-resolution white-light images, enabling the tracking of specific features of the CME through the solar corona and heliosphere. On March 28, 2022, the active region (AR) 12975, located near the solar disk center at 12 degrees to the North, displayed a filament eruption at 11:20 UT that produced an CME observed by multiple instruments. This CME displays complex characteristics in its structure detected from different points of view by the available coronagraphs and heliospheric imagers. By combining SoloHI data with the observations obtained by other remote sensing observatories located at 1 au, we perform a multi-viewpoint analysis that describes the evolution of the CME from its origin. This work aims to explain the identified structures in SoloHI observations and their correspondence in those provided by other instruments. Additionally, we perform a 3D reconstruction using the CORHEL-CME MHD model available in the Community Coordinated Modeling Center (CCMC), correlating observed structures with those in the model. Finally, we study the eruption and early interaction with the magnetic environment through flux emergence and magnetic evolution of the AR, to better understand the complexity of the final structures.
