The high-energy protons of the ground level enhancement (GLE74) event on 11 May 2024
A. Papaioannou, A. Mishev, I. Usoskin +19
High energy solar protons were observed by particle detectors aboard spacecraft in near-Earth orbit on May 11, 2024 and produced the 74th ground level enhancement (GLE74) event reg…
The Probabilistic Solar Particle Event foRecasting (PROSPER) Model
Athanasios Papaioannou, Rami Vainio, Osku Raukunen +6
The Probabilistic Solar Particle Event foRecasting (PROSPER) model predicts the probability of occurrence and the expected peak flux of Solar Energetic Particle (SEP) events. Predi…
New reconstruction of event-integrated spectra (spectral fluences) for major solar energetic particle events
Sergey A. Koldobskiy, Osku Raukunen, Rami Vainio +2
Fluences of solar energetic particles (SEPs) are not easy to evaluate, especially for high-energy events (i.e. ground-level enhancements, GLEs). Earlier estimates of event-integrat…
Updated Model of the Solar Energetic Proton Environment in Space
Piers Jiggens, Daniel Heynderickx, Ingmar Sandberg +3
The Solar Accumulated and Peak Proton and Heavy Ion Radiation Environment (SAPPHIRE) model provides environment specification outputs for all aspects of the Solar Energetic Particl…
Why is solar cycle 24 an inefficient producer of high-energy particle events?
Rami Vainio, Osku Raukunen, Allan J. Tylka +2
The aim of the study is to investigate the reason for the low productivity of high-energy SEPs in the present solar cycle. We employ scaling laws derived from diffusive shock accel…
Iron-rich solar particle events measured by SOHO/ERNE during two solar cycles
O. Raukunen, E. Valtonen, R. Vainio
We study the differences in the heavy ion composition of solar energetic particle (SEP) events between solar cycles 23 and 24. We have surveyed the SOHO/ERNE heavy ion data from th…
