Shock properties for solar energetic particle events with signatures of inverse velocity arrival
A. Kouloumvakos, D. Lario, G. M. Mason +20
We present a detailed investigation of the shock properties associated with solar energetic particle (SEP) events that exhibit a concave (``nose-like'') shape in their energy spect…
How the CME on 21 April 2023 Triggered the First Severe Geomagnetic Storm of Solar Cycle 25
Evangelos Paouris, Angelos Vourlidas, Manolis K. Georgoulis +2
The first severe (G4) geomagnetic storm of Solar Cycle 25 occurred on 23-24 April 2023, following the arrival of a Coronal Mass Ejection (CME) on 23 April. The characteristics of t…
CME Propagation Through the Heliosphere: Status and Future of Observations and Model Development
M. Temmer, C. Scolini, I. G. Richardson +31
The ISWAT clusters H1+H2 have a focus on interplanetary space and its characteristics, especially on the large-scale co-rotating and transient structures impacting Earth. SIRs, gen…
Quantifying errors in 3D CME parameters derived from synthetic data using white-light reconstruction techniques
Christine Verbeke, M. Leila Mays, Christina Kay +10
(Shortened version) Current efforts in space weather forecasting of CMEs have been focused on predicting their arrival time and magnetic structure. To make predictions, methods hav…
Parameter Distributions for the Drag-Based Modeling of CME Propagation
Gianluca Napoletano, Raffaello Foldes, Enrico Camporeale +7
In recent years, ensemble modeling has been widely employed in space weather to estimate uncertainties in forecasts. We here focus on the ensemble modeling of CME arrival times and…
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…
Facilities of Athens Neutron Monitor Station to Space Weather services
H. Mavromichalaki, M. Gerontidou, P. Paschalis +1
In the frame of the comprehensive knowledge, detection and forecasting of the solar terrestrial relations as well as space weather events, the ground based measurements of the netw…
