Three-part structure of solar coronal mass ejection observed in low coronal signatures of Solar Orbiter
Tatiana Podladchikova, Shantanu Jain, Astrid M. Veronig +4
This study examines the relationship between early solar coronal mass ejection (CME) propagation, the associated filament eruption, and coronal dimming in the rare event observed o…
Detecting and sizing the Earth with PLATO: A feasibility study based on solar data
A. F. Krenn, M. Lendl, S. Sulis +8
Context. The PLAnetary Transits and Oscillations of stars (PLATO) mission will observe the same area of the sky continuously for at least two years in an effort to detect transit s…
Estimating early coronal mass ejection propagation direction with DIRECD during the severe May 8 and follow-up June 8, 2024 events
Shantanu Jain, Tatiana Podladchikova, Astrid M. Veronig +4
On May 8, 2024, solar active region 13664 produced an X-class flare, several M-class flares, and multiple Earth-directed Coronal Mass Ejections (CMEs). The initial CME caused coron…
The observational evidence that all microflares that accelerate electrons to high energies are rooted in sunspots
Andrea Francesco Battaglia, Säm Krucker, Astrid M. Veronig +6
In general, large solar flares are more efficient at accelerating high-energy electrons than microflares. Nonetheless, we sometimes observe microflares that accelerate electrons to…
Magnetic Field Evolution of the Solar Active Region 13664
Robert Jarolim, Astrid Veronig, Stefan Purkhart +2
On 2024 May 10/11, the strongest geomagnetic storm since November 2003 has occurred, with a peak Dst index of -412 nT. The storm was caused by NOAA Active Region (AR) 13664, which…
Revisiting Empirical Solar Energetic Particle Scaling Relations II. Coronal Mass Ejections
Athanasios Papaioannou, Konstantin Herbst, Tobias Ramm +2
Aims. The space radiation environment conditions and the maximum expected coronal mass ejection (CME) speed are being assessed through the investigation of scaling laws between the…
Multipoint study of the rapid filament evolution during a confined C2 flare on 28 March 2022, leading to eruption
Stefan Purkhart, Astrid M. Veronig, Bernhard Kliem +5
We studied the rapid filament evolution in AR 12975 during a confined C2 flare on 28 March 2022, which led to an eruptive M4 flare 1.5 h later. It is characterized by the breakup o…
Generation of relativistic electrons at the termination shock in the solar flare region
G. Mann, A. M. Veronig, F. Schuller
Solar flares are accompanied by an enhanced emission of electromagnetic waves from the radio up to the gamma-ray range. The associated hard X-ray (HXR) and microwave radiation is g…
Coupling between magnetic reconnection, energy release, and particle acceleration in the X17.2 2003 October 28 solar flare
Victoria G. Kurt, Astrid M. Veronig, Gregory D. Fleishman +3
The 2003 October 28 (X17.2) eruptive flare was a unique event. The coronal electric field and the π-decay γ-ray emission flux had the highest values ever inferred in solar flares.…
Stability of the coronal magnetic field around large confined and eruptive solar flares
Manu Gupta, J. K. Thalmann, A. M. Veronig
In order to improve our understanding on the pre-requisites of eruptive solar flares, we study and compare different measures that characterize the eruptive potential of solar acti…
Internal magnetic field structures observed by PSP/WISPR in a filament related coronal mass ejection
G. M. Cappello, M. Temmer, A. Vourlidas +7
We track and investigate from white-light data taken with the Wide-field Instrument for Solar PRobe (WISPR) aboard Parker Solar Probe (PSP), localized density enhancements, reflect…
The Plasma in quiet Sun Regions: Multi-Instrument View
Jenny M. Rodríguez-Gómez, Christoph Kuckein, Sergio J. Gonzalez Manrique +4
A joint campaign of several space-borne and ground-based observatories, such as the GREGOR solar telescope, the Extreme-ultraviolet Imaging Spectrometer (EIS), and the Interface Re…
Unveiling the Journey of a Highly Inclined CME: Insights from the March 13, 2012 Event with 110 Longitudinal Separation
F. Carcaboso, M. Dumbovic, C. Kay +8
A fast and wide Coronal Mass Ejection (CME) erupted from the Sun on 2012-03-13. Its interplanetary counterpart was detected in situ two days later by STEREO-A and near-Earth spacec…
Instrument-To-Instrument translation: Instrumental advances drive restoration of solar observation series via deep learning
Robert Jarolim, Astrid M. Veronig, Werner Pötzi +1
The constant improvement of astronomical instrumentation provides the foundation for scientific discoveries. In general, these improvements have only implications forward in time,…
The Link Between Non-Thermal Velocity and Free Magnetic Energy in Solar Flares
James McKevitt, Robert Jarolim, Sarah Matthews +5
The cause of excess spectral line broadening (non-thermal velocity) is not definitively known, but given its rise before and during flaring, the causal processes hold clues to unde…
