Description
We present an updated catalog of interplanetary coronal mass ejections (ICMEs) detected by Parker Solar Probe (PSP) and/or Solar Orbiter (SolO) during the period 2020 to 2023. These new generation of solar missions provide an unprecedented perspective on solar transients, enabling multi-point observations, and enhancing our understanding of CME evolution and propagation in the interplanetary medium. We identified potential ICMEs in the Moon-to-Mars (M2M) CME catalog populated by the M2M Space Weather Analysis Office. The team analyze CME events in real-time and predict arrivals that may have impact to different NASA missions. This catalog is available in the Space Weather Database Of Notifications, Knowledge, Information (DONKI) developed at the Community Coordinated Modeling Center (CCMC). For each event, we cross-checked the expected time arrival with the actual arrival detected in PSP or SolO data, based mainly on solar wind plasma values and magnetic field parameters. We then link and track the ICME with its counterpart CME observed by the coronagraphs LASCO-C2/C3 and COR1/2, and detail, when possible, the associated solar source. Additionally, we conducted a statistical analysis of two key aspects: the differences between predicted and observed ICME arrival times, and the deviation from the solar source location and estimated propagation angle reported by the M2M team. With the combination of remote sensing and in-situ measurements, the Solar Orbiter and Parker Solar Probe mission contribute to the study of coronal mass ejections and other structures in the inner heliosphere, making a huge contribution in the understanding of these structures, as well as in the multi-viewpoint studies.
