Solar Energetic Particles (SEPs)
SOHO/ERNE E>100 MeV protons
Description: This catalogue presents a comprehensive list of >100 MeV solar proton events observed between May 1996 and August 2024 using data from SOHO / ERNE. The events were systematically identified and cross-calibrated to determine their key properties, such as peak flux and fluence. Each event was linked to its most likely solar source by combining multi-instrument observations, including X-ray measurements (e.g. GOES), radio data (e.g. Wind), gamma-ray observations (Fermi), coronal mass ejections observed by SOHO / LASCO, and ground-based neutron monitors. By comparing the timing and physical properties of these phenomena, the catalogue supports investigations into how high-energy proton events relate to solar flares, CMEs, and radio bursts

SolO/HET
Description: The SPEARHEAD SolO/HET Catalogue provides a comprehensive list of Solar Energetic Particle (SEP) events observed by the High Energy Telescope (HET) aboard Solar Orbiter. The catalogue includes onset, peak intensity, and fluence measurements for electrons (~1 MeV and 5.99–18.83 MeV) and protons (~8, ~25, and ~50 MeV), together with elemental abundance indicators, associated solar flares and CMEs, solar wind and magnetic field conditions, and particle release analyses based on Time Shifting Analysis (TSA) and Velocity Dispersion Analysis (VDA) methods.

SOHO/EPHIN E~3.8 MeV electrons
Description: The SPEARHEAD SOHO/EPHIN Solar Energetic Electron Catalogue contains 135 solar energetic electron (SEE) events observed at approximately 3.8 MeV between 1997 and 2017. Built upon the SPEARHEAD >100 MeV proton event list, the catalogue provides electron onset times, peak fluxes, fluences, spacecraft location parameters, and associated event information in a standardized format, enabling detailed studies of SEP acceleration, transport, and solar source associations.
Ulysses/KET
Description: The SPEARHEAD Ulysses/KET Solar Energetic Electron Catalogue contains 13 high-energy solar energetic electron (SEE) events identified during the Ulysses mission (1990–2009). The catalogue combines observations from the Kiel Electron Telescope (KET) and High Energy Telescope (HET), providing event onset times, peak intensities, fluences, and spacecraft location information across a wide range of heliographic latitudes. These rare events offer valuable insights into particle acceleration and transport processes throughout the heliosphere.
Forbush Decreases
Forbush decreases
Description: Forbush decrease catalogue (FDcat) of measured flux-rope related Forbush decreases in Helios, Solar Orbiter, Ulysses, SOHO, South Pole neutron monitor and MSL/RAD.
