The existence of hot X-ray onsets in solar flares
Andrea Francesco Battaglia, Hugh Hudson, Alexander Warmuth +9
It is well known among the scientific community that solar flare activity often begins well before the main impulsive energy release. Our aim is to investigate the earliest phase o…
A multiple spacecraft detection of the 2 April 2022 M-class flare and filament eruption during the first close Solar Orbiter perihelion
M. Janvier, S. Mzerguat, P. R. Young +56
The Solar Orbiter mission completed its first remote-sensing observation windows in the spring of 2022. On 2/4/2022, an M-class flare followed by a filament eruption was seen both…
Observational signatures of electron-driven chromospheric evaporation in a white-light flare
Dong Li, Chuan Li, Ye Qiu +7
We investigate observational signatures of explosive chromospheric evaporation during a white-light flare (WLF) that occurred on 2022 August 27. Using the moment analysis, bisector…
The Focusing Optics X-ray Solar Imager (FOXSI)
Steven Christe, Meriem Alaoui, Joel Allred +26
FOXSI is a direct-imaging, hard X-ray (HXR) telescope optimized for solar flare observations. It detects hot plasma and energetic electrons in and near energy release sites in the…
Magnetic Energy Powers the Corona: How We Can Understand its 3D Storage & Release
Amir Caspi, Daniel B. Seaton, Roberto Casini +12
The coronal magnetic field is the prime driver behind many as-yet unsolved mysteries: solar eruptions, coronal heating, and the solar wind, to name a few. It is, however, still poo…
Improving Multi-Dimensional Data Formats, Access, and Assimilation Tools for the Twenty-First Century
Daniel B. Seaton, Amir Caspi, Roberto Casini +12
Heliophysics image data largely relies on a forty-year-old ecosystem built on the venerable Flexible Image Transport System (FITS) data standard. While many in situ measurements us…
COMPLETE: A flagship mission for complete understanding of 3D coronal magnetic energy release
Amir Caspi, Daniel B. Seaton, Roberto Casini +12
COMPLETE is a flagship mission concept combining broadband spectroscopic imaging and comprehensive magnetography from multiple viewpoints around the Sun to enable tomographic recon…
Global energetics of solar powerful events on 6 September 2017
Dong Li, Alexander Warmuth, Jincheng Wang +9
Solar flares and coronal mass ejections (CMEs) are thought to be the most powerful events on the Sun. They can release energy as high as 10^32 erg in tens of minutes,and could prod…
The 17 April 2021 widespread solar energetic particle event
N. Dresing, L. Rodríguez-García, I. C. Jebaraj +46
Context. A solar eruption on 17 April 2021 produced a widespread Solar Energetic Particle (SEP) event that was observed by five longitudinally well-separated observers in the inner…
Parametric study of the kinematic evolution of coronal mass ejection shock waves and their relation to flaring activity
Manon Jarry, Alexis P. Rouillard, Illya Plotnikov +2
Coronal and interplanetary shock waves produced by coronal mass ejections (CMEs) are major drivers of space-weather phenomena, inducing major changes in the heliospheric radiation…
STIX imaging I -- Concept
Paolo Massa, Gordon. J. Hurford, Anna Volpara +17
Aims. To provide a schematic mathematical description of the imaging concept of the Spectrometer/Telescope for Imaging X-rays (STIX) on board Solar Orbiter. The derived model is th…
Multi-point study of the energy release and impulsive CME dynamics in an eruptive C7 flare
J. Saqri, A. M. Veronig, E. C. M. Dickson +6
We combine observations from different vantage points to perform a detailed study of a long duration eruptive C7 class flare that occurred on 17 April 2021 and was partially occult…
The data center for the Spectrometer and Telescope for Imaging X-rays (STIX) onboard Solar Orbiter
Hualin Xiao, Shane Maloney, Säm Krucker +12
The Spectrometer and Telescope for Imaging X-rays (STIX) on board Solar Orbiter observes solar X-ray emission in the range of 4 – 150 keV and produces spectra and images of s…
Multiple injections of energetic electrons associated with the flare/CME event on 9 October 2021
Immanuel Christopher Jebaraj, Athanasios Kouloumvakos, Nina Dresing +11
We study the solar energetic particle (SEP) event observed on 9 October 2021, by multiple spacecraft including Solar Orbiter (SolO). The event was associated with an M1.6 flare, a…
