Understanding the Complex Morphology of a Coronal Mass Ejection. III: How to Create a Severe Geomagnetic Storm
Cecilia Mac Cormack, Abril Sahade, Erika Palmerio +4
On April 21, 2023, a complex filament eruption produced an Earth-directed coronal mass ejection (CME) that triggered the first severe geomagnetic storm of solar cycle 25. The prima…
The First Quantitative Study of Tail Regrowth of CME-Driven Disconnection in Comet C/2023 P1 Nishimura
Shaheda Begum Shaik, Guillermo Stenborg, Phillip Hess +3
Comet C/2023 P1 (Nishimura) was observed by the Solar Orbiter Heliospheric Imager (SoloHI), onboard the Solar Orbiter spacecraft, from 2023 September 1 to 14. During this period, t…
Understanding the complex morphology of a CME: multi-view analysis and numerical modeling
Cecilia Mac Cormack, Abril Sahade, Angelos Vourlidas +3
Although all coronal mass ejections (CMEs) that propagate into the heliosphere should contain a magnetic flux rope (MFR) component, the majority do not exhibit the expected white-l…
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…
