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…
Propagating Conditions and the Time of ICMEs Arrival: A Comparison of the Effective Acceleration Model with ENLIL and DBEM Models
Evangelos Paouris, Jasa Calogovic, Mateja Dumbovic +5
The Effective Acceleration Model (EAM) predicts the Time-of-Arrival (ToA) of the Coronal Mass Ejection (CME) driven shock and the average speed within the sheath at 1 AU. The model…
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…
Comparing the Properties of ICME-Induced Forbush Decreases at Earth and Mars
Johan L. Freiherr von Forstner, Jingnan Guo, Robert F. Wimmer-Schweingruber +9
Forbush decreases (FDs), which are short-term drops in the flux of galactic cosmic rays, are caused by the shielding from strong and/or turbulent magnetic structures in the solar w…
Sources of Solar Energetic Particles
Loukas Vlahos, Anastasios Anastasiadis, Athanasios Papaioannou +2
Solar Energetic Particles (SEP) are an integral part of the physical processes related with Space Weather. We present a review for the acceleration mechanisms related to the explos…
Catalogue of >55 MeV Wide-longitude Solar Proton Events Observed by SOHO, ACE, and the STEREOs at 1 AU during 2009-2016
Miikka Paassilta, Athanasios Papaioannou, Nina Dresing +3
Based on energetic particle observations made at 1 AU, we present a catalogue of 46 wide-longitude (>45°) solar energetic particle (SEP) events detected at multiple locati…
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…
Catalogue of 55-80 MeV solar proton events extending through solar cycles 23 and 24
Miikka Paassilta, Osku Raukunen, Rami Vainio +9
We present a new catalogue of solar energetic particle events near the Earth, covering solar cycle 23 and the majority of solar cycle 24 (1996-2016), based on the 55-80 MeV proton…
Mapping of the cosmic ray events related to the solar activity for the period 2003-2005
A. Papaioannou, P. Makrantoni, H. Mavromichalaki
The relationship between cosmic ray intensity decreases and solar events is still an open field of space research. In this work a complete study of solar events occurred from Janua…
