New Solar Orbiter Solar Energetic Particle Event Catalogue Released on Zenodo

We are pleased to announce the release of the new Solar Energetic Particle (SEP) event catalogue based on observations from ESA/NASA’s Solar Orbiter mission. The catalogue is now openly available through Zenodo and provides the scientific community with a valuable resource for the study of SEP events during Solar Cycle 25.

SPEARHEAD highlights new advances in heliophysics research at EGU2026

The SPEARHEAD Horizon Europe project participated actively in the EGU General Assembly 2026, presenting a broad range of new scientific results related to Solar Energetic Particles (SEPs), Forbush decreases (FDs), CME-driven shocks, particle transport, and heliospheric modelling. Through oral presentations and posters, SPEARHEAD researchers showcased recent advances based on multi-spacecraft observations, simulations, catalogues, and open-source analysis tools.
