Abstract: Coronal Mass Ejections (CMEs) are major drivers of heliospheric variability and pose significant risks to spacecraft, planetary environments, and future human exploration. Understanding their initiation and evolution requires coordinated, multi-spacecraft observations capable of capturing their three-dimensional structure and propagation through the heliosphere. We present a living multi-view and multi-point catalog of CMEs detected by Solar Orbiter during the rising phase of Solar Cycle 25 (2019–2024). The catalog combines remote-sensing and in situ measurements from Solar Orbiter, Parker Solar Probe, STEREO-A, SOHO, and Wind, including CME source properties, observations of its evolution, interplanetary signatures, and associations with energetic particles and radio events. These data are complemented by models and reports available in the Space Weather Database Of Notifications, Knowledge, Information (DONKI) provided by the Moon to Mars (M2M) Space Weather Analysis Office. Maintaining a dedicated Solar Orbiter CME catalog is essential to improve our understanding of CME dynamics and their space weather impact. This work highlights the importance of multi-spacecraft collaboration, a core aspect of the mission, in achieving comprehensive CME coverage and underscores the value of open, coordinated data analysis as we prepare for a new era of sustained human presence in space.
