Photospheric Lorentz force changes in eruptive and confined solar flares
Samriddhi Sankar Maity, Ranadeep Sarkar, Piyali Chatterjee +1
Solar flares are known to leave imprints on the magnetic field at the photosphere, often manifested as an abrupt and permanent change in the downward-directed Lorentz force in loca…

The Automatic Identification and Tracking of Coronal Flux Ropes -- Part II: New Mathematical Morphology-based Flux Rope Extraction Method and Deflection Analysis
Andreas Wagner, Slava Bourgeois, Emilia K. J. Kilpua +9
We present a magnetic flux rope (FR) extraction tool for solar coronal magnetic field modelling data, which builds upon the methodology from Wagner et al. (2023). We apply the sche…

Studying the spheromak rotation in data-constrained CME modelling with EUHFORIA and assessing its effect on the Bz prediction
Ranadeep Sarkar, Jens Pomoell, Emilia Kilpua +4
A key challenge in space weather forecasting is accurately predicting the magnetic field topology of interplanetary coronal mass ejections (ICMEs), specifically the north-south mag…
