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…
The First Ground Level Enhancement of Solar Cycle 25 on 28 October 2021
A. Papaioannou, A. Kouloumvakos, A. Mishev +8
Aims. The first relativistic solar proton event of solar cycle 25 (SC25) was detected on 28 October 2021 by neutron monitors (NMs) on the ground and particle detectors onboard spac…
Radial Evolution of the April 2020 Stealth Coronal Mass Ejection between 0.8 and 1 AU -- A Comparison of Forbush Decreases at Solar Orbiter and Earth
Johan L. Freiherr von Forstner, Mateja Dumbović, Christian Möstl +40
Aims. We present observations of the first coronal mass ejection (CME) observed at the Solar Orbiter spacecraft on April 19, 2020, and the associated Forbush decrease (FD) measured…
Assessing the projection correction of Coronal Mass Ejection speeds on Time-of-Arrival prediction performance using the Effective Acceleration Model
Evangelos Paouris, Angelos Vourlidas, Athanasios Papaioannou +1
White light images of Coronal Mass Ejections (CMEs) are projections on the plane-of-sky (POS). As a result, CME kinematics are subject to projection effects. The error in the true…
From Starspots to Stellar Coronal Mass Ejections -- Revisiting Empirical Stellar Relations
Konstantin Herbst, Athanasios Papaioannou, Vladimir S. Airapetian +1
Upcoming missions, including the James Webb Space Telescope, will soon characterize the atmospheres of terrestrial-type exoplanets in habitable zones around cool K- and M-type star…
The Solar Orbiter Science Activity Plan: translating solar and heliospheric physics questions into action
I. Zouganelis, A. De Groof, A. P. Walsh +182
Solar Orbiter is the first space mission observing the solar plasma both in situ and remotely, from a close distance, in and out of the ecliptic. The ultimate goal is to understand…
Evidence for a Coronal Shock Wave Origin for Relativistic Protons Producing Solar Gamma-Rays and Observed by Neutron Monitors at Earth
Athanasios Kouloumvakos, Alexis P. Rouillard, Gerald H. Share +4
We study the solar eruptive event on 2017 September 10 that produced long-lasting 100 MeV -ray emission and a ground level enhancement (GLE72). The origin of the high-energy…
Measurements of Forbush decreases at Mars: both by MSL on ground and by MAVEN in orbit
Jingnan Guo, Robert Lillis, Robert F. Wimmer-Schweingruber +13
The Radiation Assessment Detector (RAD), on board Mars Science Laboratory's (MSL) Curiosity rover, has been measuring ground level particle fluxes along with the radiation dose rat…
