10. The ESA Vigil Mission at L5:Heliospheric Modelling Opportunities from a New Perspective

Matthew West (European Space Agency)

07/04/2026, 10:00

In-person oral presentation

The ESA Vigil mission will be the first operational space weather mission positioned at the Sun-Earth L5 Lagrange point. From this unique vantage point, Vigil will continuously observe solar activity and monitor regions near the Sun-Earth line, enhancing both near real-time space weather nowcasting and forecasting, as well as long-term scientific studies. This presentation will provide an...

9. Space weather forecasting with sub-L1 solar wind monitors

Christian Möstl (Austrian Space Weather Office, GeoSphere Austria, Graz, Austria)

07/04/2026, 10:15

In-person oral presentation

I will present the pipelines at the Austrian Space Weather Office for solar wind forecasting, using a combination of empirical-, physics- and data based models for modeling the propagation, automatic detection and flux rope characterization of CMEs (ELEvo(HI), ARCANE, 3DCORE). A particular emphasis is given on the usage of sub-L1 and far upstream data, which has just recently become available...

22. Operational Machine-Learning-Enhanced CME Arrival-Time Forecasting and In-Situ ICME Detection

Sabrina Guastavino (sabrina.guastavino@unige.it)

07/04/2026, 10:30

In-person oral presentation

Accurate and timely forecasts of coronal mass ejection (CME) arrival times at Earth are are essential for operational space weather services aimed at mitigating impacts on spacecraft, ground-based infrastructure, and radiation-sensitive systems. We present two complementary machine-learning-based tools that address both CME arrival-time prediction and the identification of interplanetary CMEs...

38. Variational Data Assimilation for Improved 3D Global MHD Forecasting of the Ambient Solar Wind

Jose Arnal (University of Toronto)

07/04/2026, 10:45

In-person oral presentation

Over the past several decades, there has been a growing recognition of the adverse impacts that space weather can pose to human infrastructure, activity, and health. Consequently, as modern society becomes increasingly reliant on vulnerable technological systems, there is a corresponding demand for accurate and reliable space weather forecasting capabilities. Successful space weather...

36. Architectural and Performance Optimization of the Energetic Particle Radiation Environment Model (EPREM-CPP)

Mr Artem Epifanov (Institute of Astronomy and National Astronomical Observatory, Bulgarian Academy of Sciences)

07/04/2026, 11:00

In-person oral presentation

We have performed a comprehensive redesign of the Energetic Particle Radiation Environment Model (EPREM) to address certain limitations of the original implementation. This new implementation, written in C++, introduces enhancements to address grid resampling artifacts at the inner boundary, as well as time-variable, pitch-anisotropic, and spatially-distributed seed functions to simulate...
