Solar Energetic Particle Events Including ∼ 25 MeV Protons Observed at STEREO and/or Earth since 2006

This file lists the solar energetic particle events that include ∼ 25 MeV protons detected at STEREO A/B or at the Earth since the beginning of the STEREO mission in October 2006, based predominantly on examination of ∼ 1 hour-averaged observations from the HET instruments on the STEREO spacecraft and from the ERNE and COSTEP instruments on SOHO. This is an updated and expanded version of the catalog in “> 25 MeV Proton Events Observed by the High Energy Telescopes on the STEREO A and B Spacecraft and/or at the Earth During the First ∼Seven Years of the STEREO Mission” by I. G. Richardson, T. T. von Rosenvinge, H. V. Cane, E. R. Christian, C. M. S. Cohen, A. W. Labrador, R. A. Leske, R. A. Mewaldt, M. E. Wiedenbeck,
