Overview

Single-Point Catalogs

The magnetic topology, structure, and geometry of magnetic obstacles embedded within interplanetary coronal mass ejections (ICMEs) are not yet fully or consistently characterized by current in situ models and reconstruction techniques. The primary goal of this work is to improve our understanding of the internal magnetic field structure of ICMEs and to identify in situ signatures that can guide the development of more accurate and reliable analytical models.

These catalogs report key ICME properties, including disturbance arrival time, magnetic obstacle start time, duration, mean magnetic field strength, mean obstacle speed, mean proton density, apparent expansion velocity, distortion parameter, and magnetic obstacle classification.

Multi-viewpoint Catalogs

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.

Multi-viewpoint ICMEs identified from Solar Orbiter Heliospheric Imager (SoloHI) observations of visible light scattered by solar wind electrons.

The Solar Orbiter Heliospheric Imager (SoloHI), developed and operated by the U.S. Naval Research Laboratory (NRL), is one of the six remote-sensing instruments aboard Solar Orbiter. It observes visible light scattered by electrons in the solar wind.

This catalog is based on SoloHI observations and adopts a multi-viewpoint approach. For each detected event, we link in situ and remote-sensing observations from multiple missions, identify the CME source region and describe its main properties, track its evolution across coronagraphs and heliospheric imagers, provide plots for events detected in situ by different spacecraft and complement observations with modeling results from the Space Weather Database Of Notifications, Knowledge, Information (DONKI), developed at the Community Coordinated Modeling Center (CCMC).

A comprehensive, evolving catalog of CMEs detected in situ by Solar Orbiter during the rising phase of Solar Cycle 25 (2019–2025).

This is a comprehensive and evolving catalog of CMEs detected in situ by Solar Orbiter, focusing on the rising phase of Solar Cycle 25 (2019–2025). Its goal is to provide a unified multi-view and multi-point resource for studying CME dynamics, evolution, and space weather impacts.

The catalog combines data from multiple spacecraft, including Solar Orbiter, Parker Solar Probe (PSP), STEREO-A, SOHO, SDO, Wind, and MAVEN. It integrates remote-sensing and in situ observations to document CME source properties, interplanetary evolution, and associations with energetic particles and radio emissions. Additionally, modeling results and reports from DONKI, provided by the Moon to Mars (M2M) Space Weather Analysis Office, are incorporated to complement the observational dataset.
