COSPAR-2024: Understanding and Predicting Solar Energetic Particle Events Across the Heliosphere (D1.6)

Dear colleagues,

We would like to bring your attention to the COSPAR-24-D1.6 Scientific Event on the Understanding and Predicting Solar Energetic Particle Events Across the Heliosphere that will take place at the upcoming COSPAR 2024 45th Scientific Assembly ( from 13 – 21 July 2024 in Busan, Korea.

Solar Energetic Particle (SEP) events pose a significant threat to space weather and human space exploration. Understanding and predicting these events are crucial for minimizing their impact. This session will bring together researchers in the field to discuss the latest advancements in SEP research, including observations, theoretical modeling, and data analysis techniques. We will address several key topics, such as the acceleration mechanisms of SEPs and their transport through the turbulent solar wind. Additionally, we will explore methods for predicting the occurrence, duration, and intensity of SEP events, including advancements in space weather forecasting. Our goal is to foster collaboration among scientists and to develop a comprehensive understanding of SEP events that will enhance our ability to predict and mitigate their effects.

In this session, we invite contributions on models and observations of SEPs, covering their initiation by solar eruptive events, acceleration, injection, transport and prediction of their occurrence and corresponding characteristics at Earth and other planets. The session focuses on key developments that address SEP forecasting at different time scales.

We solicit contributions related to:
• The acceleration of particles to space weather relevant energies, including the relative role of reconnection, compressions and shocks.
• Modeling particle acceleration and transport in the corona and the inner heliosphere.
• Multi-spacecraft observations of SEP events across the heliosphere (using e.g. Helios, Parker Solar Probe, Solar Orbiter, BepiColombo, L1, Mars, and beyond)
• Predicting the occurrence and characteristics of SEP events (including physics-based, data-driven, and machine learning approaches).
• Modeling and predicting the evolution of the SEP time profile.
• Capabilities to predict SEP events across the heliosphere.

The abstract submission is currently open and abstracts will continue to be accepted up until 09 February 2024 (
