Evolution of the critical torus instability height and CME likelihood in solar active regions
Alexander W. James, David R. Williams, Jennifer O'Kane
Aims. Working towards improved space weather predictions, we aim to quantify how the critical height at which the torus instability drives coronal mass ejections (CMEs) varies over…
Understanding the Origins of Problem Geomagnetic Storms Associated With "Stealth" Coronal Mass Ejections
Nariaki V. Nitta, Tamitha Mulligan, Emilia K. J. Kilpua +14
Geomagnetic storms are an important aspect of space weather and can result in significant impacts on space- and ground-based assets. The majority of strong storms are associated wi…
Localised acceleration of energetic particles by a weak shock in the solar corona
David M. Long, Hamish A. S. Reid, Gherardo Valori +1
Globally-propagating shocks in the solar corona have long been studied to quantify their involvement in the acceleration of energetic particles. However, this work has tended to fo…
Investigating Remote-sensing Techniques to Reveal Stealth Coronal Mass Ejections
Erika Palmerio, Nariaki V. Nitta, Tamitha Mulligan +7
Eruptions of coronal mass ejections (CMEs) from the Sun are usually associated with a number of signatures that can be identified in solar disc imagery. However, there are cases in…
Solar origins of a strong stealth CME detected by Solar Orbiter
Jennifer O'Kane, Lucie M. Green, Emma E. Davies +6
Aims.We aim to locate the origin of a stealth coronal mass ejection (CME) detected in situ by the MAG instrument on board Solar Orbiter, and make connections between the CME observ…
The Magnetic Environment of a Stealth Coronal Mass Ejection
Jennifer O'Kane, Cecilia Mac Cormack, Cristina H. Mandrini +4
Interest in stealth coronal mass ejections (CMEs) is increasing due to their relatively high occurrence rate and space weather impact. However, typical CME signatures such as extre…
Stealth Coronal Mass Ejections from Active Regions
Jennifer O'kane, Lucie Green, David M. Long +1
Stealth coronal mass ejections (CMEs) are eruptions from the Sun that have no obvious low coronal signature. These CMEs are characteristically slower events, but can still be geoef…
