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.

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.

Today at the EGU General Assembly 2026, Dr. Manon Jarry (Postdoctoral researcher at NOA) delivered an oral presentation in the session “ST1.8 Acceleration and Transport of Suprathermal and Energetic Particles in the Heliosphere”. Her talk, titled “Proton acceleration by CME-driven shock during the 21 November 2024 (GLE76) event”, focused on one of the most intriguing recent solar energetic particle events.

We are pleased to announce the SPEARHEAD School that will take place from 04-08 September 2026 at Kiel, Germany – hosted by the Christian Albrechts Universitat zu Kiel (CAU). The School will provide hands-on training with SPEARHEAD tools and data, offering participants a practical and interactive learning experience

The Horizon Europe project SPEARHEAD (SPEcification, Analysis & Re-calibration of High Energy pArticle Data) has successfully completed its second Interim Report Meeting (IRM2), marking another major milestone in the project’s lifecycle.

A new catalogue of >100 MeV solar energetic proton events Within the framework of the SPEARHEAD project, we present a new catalogue of high energy particles observed by SOHO/ERNE in the last three solar cycles (1996–2024), with protons of >100 MeV.
