Comprehensive MHD modelling of ten successive CMEs driving a historic geomagnetic storm -- The 2024 Mothers Day event
Shirsh Lata Soni, Anwesha Maharana, Sanchita Pal +1
Interacting coronal mass ejections (CMEs) result in complex heliospheric structures that can dramatically enhance their geoeffectiveness compared to isolated events. A striking exa…
Rotation of flux ropes in the low corona
Brigitte Schmieder, Anwesha Maharana, Jin Han Guo +2
Eruptions of filaments are defined by different parameters, specially, sigmoid handedness and direction of the eruption, which are important parameters for forecasting the geoeffec…
Flare energetics, CME launch and heliospheric propagation for the May 2024 events, as derived from ensemble MHD modelling
Brigitte Schmieder, Jinhan Guo, Guillaume Aulanier +2
Many questions must be answered before understanding the relationship between the emerging magnetic flux through the solar surface and the extreme geoeffective events. The main ing…
Toroidal modified Miller-Turner CME model in EUHFORIA: II. Validation and comparison with flux rope and spheromak
Anwesha Maharana, Luis Linan, Stefaan Poedts +1
Rising concerns about the impact of space weather-related disruptions demand modelling and reliable forecasting of coronal mass ejection (CME) impacts. In this study, we demonstrat…
Validation of EUHFORIA cone and spheromak Coronal Mass Ejection Models
L. Rodriguez, D. Shukhobodskaia, A. Niemela +15
Aims. We present the validation results for arrival times and geomagnetic impact of Coronal Mass Ejections (CMEs), using the cone and spheromak CME models implemented in EUropean H…
