Dear colleagues,

We would like to bring your attention to the COSPAR-22-D1.3 Scientific Event on the Understanding and Predicting Solar Energetic Particle Events Across the Heliosphere ( that will take place in the coming July 2022 at Athens, Greece during COSPAR 2022 44th Scientific Assembly (

Abstract: The study of Solar Energetic Particles (SEP) and their impacts on Earth and other planets has made significant progress in the last decade due to: (a) an armada of spacecraft delivering observations from different vantage points within the heliosphere; (b) high performance numerical simulations and (c) extensive analysis efforts. These advances enable the detailed study of SEPs from their birth and acceleration in solar eruptive events to their acceleration, injection and transport in the interplanetary space. They can also be used for the prediction of SEPs.

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:
• Acceleration of particles to space weather relevant energies. 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 (Helios, Parker Solar Probe, Solar Orbiter, BepiColombo, L1, Mars and beyond)
• Predicting the occurrence and characteristics of SEP events
• Modeling and Predicting the evolution of the SEP time profile
• Capabilities to predict SEP events across the heliosphere

The abstract submission deadline:11 February 2022
