SERPENTINE catalog of solar cycle 25 multi-spacecraft solar energetic particle events

This catalog contains multi-spacecraft solar energetic particle (SEP) events, which were observed with the new heliospheric spacecraft fleet in solar cycle 25. It has been created within the European Union’s Horizon 2020 project SERPENTINE (Solar energetic particle analysis platform for the inner heliosphere). The catalog comprises key SEP characteristics observed by five different observer locations as provided by Solar Orbiter, Parker Solar Probe, STEREO A, Wind and SOHO (at the Lagrangian point 1), and BepiColombo. It focuses on large events, which show energetic proton increases above 25 MeV observed at least at two spacecraft. The catalog provides not only key parameters of the proton event but also the same parameters for 1 MeV and 100 keV electrons, respectively.

The csv files provided here are archived versions of the dynamic catalog available at https://data.serpentine-h2020.eu/catalogs/sep-sc25/

Provided are two semicolon-separated csv files containing the same data. The only difference is that the file sep-sc25_extended_header.csv includes an extensive header.
