A stray light analysis for SO/PHI-HRT and an updated comparison of the inferred magnetic field with SDO/HMI
Jonas Sinjan, Tino L. Riethmüller, Achim Gandorfer +6
Context. The High Resolution Telescope of the Polarimetric and Helioseismic Imager on Solar Orbiter (SO/PHI-HRT) operates in an extreme observational environment, observing the Sun…
The Non-Eruptive Reconfiguration of a Quiescent Filament After a Nearby Active Region Emergence
James McKevitt, Louise Harra, Gherardo Valori +13
The unpredictability of solar filament eruptions presents major challenges for forecasting space weather, as such eruptions frequently drive coronal mass ejections (CMEs) that impa…
Observational Evidence of S-Web Source of the Slow Solar Wind
D. Baker, P. Demoulin, S. L. Yardley +25
From 2022 March 18-21, active region (AR) 12967 was tracked simultaneously by Solar Orbiter (SO) at 0.35 au and Hinode/EIS at Earth. During this period, strong blue-shifted plasma…
Evolution of Plasma Composition in an Eruptive Flux Rope
Deborah Baker, Lucie M. Green, David H. Brooks +8
Magnetic flux ropes are bundles of twisted magnetic field enveloping a central axis. They harbor free magnetic energy and can be progenitors of coronal mass ejections (CMEs), but i…
On the Origin of Magnetic Pertubations associated with the FIP effect
M. Murabito, M. Stangalini, D. Baker +9
In \citet{Stangalini20} and \citet{Deb20}, magnetic oscillations were detected in the chromosphere of a large sunspot and found to be linked to the coronal locations where a First…
Spectropolarimetric Fluctuations in a Sunspot Chromosphere
M. Stangalini, D. Baker, G. Valori +8
The instrumental advances made in this new era of 4-meter class solar telescopes with unmatched spectropolarimetric accuracy and sensitivity, will enable the study of chromospheric…
On-disc Observations of Flux Rope Formation Prior to its Eruption
A. W. James, L. M. Green, E. Palmerio +6
Coronal mass ejections (CMEs) are one of the primary manifestations of solar activity and can drive severe space weather effects. Therefore, it is vital to work towards being able…
Flux cancellation and the evolution of the eruptive filament of 2011 June 7
S. L. Yardley, L. M. Green, D. R. Williams +3
We investigate whether flux cancellation is responsible for the formation of a very massive filament resulting in the spectacular 2011 June 7 eruption. We analyse and quantify the…
Coronal magnetic reconnection driven by CME expansion -- the 2011 June 7 event
L. van Driel-Gesztelyi, D. Baker, T. Torok +10
Coronal mass ejections (CMEs) erupt and expand in a magnetically structured solar corona. Various indirect observational pieces of evidence have shown that the magnetic field of CM…
Initiation of Coronal Mass Ejections by Sunspot Rotation
Tibor Török, Manuela Temmer, Gherardo Valori +3
We study a filament eruption, two-ribbon flare, and coronal mass ejection (CME) that occurred in Active Region NOAA 10898 on 6 July 2006. The filament was located South of a strong…
Testing magnetofrictional extrapolation with the Titov-Démoulin model of solar active regions
G. Valori, B. Kliem, T. Török +1
We examine the nonlinear magnetofrictional extrapolation scheme using the solar active region model by Titov and Démoulin as test field. This model consists of an arched, line-tied…
