Explanation of Columns
The event list is compiled by Dr. Lan Jian (lan.jian AT nasa.gov) for a reference purpose. Dr. Tarik Salman assisted in the compilation of the list for the events in 2020-2023. Dr. Noe Lugaz updated ICMEs in 2024-2025. Not all the desired data are available, such as the particle composition data, for event identifiction. Not all the events are magnetic clouds in which there are low-β and well-organized flux ropes. Some of the ICME events are arguable. For event details and ambiguous event, please consult Dr. Lan Jian. If there is a shock at the edge, the time is usually set at the closest minute.
- The criteria of event classification are published in the following papers. The results of STEREO ICME survey in 2007-2016 are published in the 2018 ApJ paper.

- ( ): values are from the region including the sheath region when the values in the sheath are higher than in the obstacle.
- ? Ambiguous event.
- * Hybrid event.
- Magnetic obstacle (~flux rope) start time1: if it is different from the ICME start time, there is a sheath region. NaN indicates there is no clear magnetic obstacle, possibly because of a glance through of the sheath region.
- ΔV: temporal variation of solar wind speed over one event, negative value indicating solar wind is expanding, and "~" means the solar wind speed remains almost constant or does not change systematically over the event despite back-and-forth changes.
- Group3: We sort ICMEs into 3 groups depending on their temporal profiles of Pt. Corresponding to the Group 1, 2, and 3 ICMEs, the Pt profile, excluding any shock and/or sheath region (if present), respectively, has a central pressure maximum, a steady plateau, or a gradual decay. In the hypothesis that all ICMEs have a central flux rope, these three groups of Pt profiles are due to different approach distances to the central flux rope. Group 1 ICMEs are assumed to be the ones penetrated by spacecraft near the flux rope axis, and they
