Solar flare hard X-rays from the anchor points of an eruptive filament
Muriel Zoë Stiefel, Andrea Francesco Battaglia, Krzysztof Barczynski +7
Context. We present an analysis of a GOES M1.8 flare with excellent observational coverage in UV, EUV, and X-ray, including observations from the instruments IRIS, SDO with AIA, Hi…
Identifying the energy release site in a Solar microflare with a jet
Andrea Francesco Battaglia, Wen Wang, Jonas Saqri +10
One of the main science questions of the Solar Orbiter and Parker Solar Probe missions deals with understanding how electrons in the lower solar corona are accelerated and how they…
Flares detected in ALMA single-dish images of the Sun
I. Skokić, A. O. Benz, R. Brajša +3
The (sub)millimeter radiation of solar flares is poorly understood. Without spatial resolution, it cannot be compared easily to flare emissions in other wavelengths. The Atacama La…
Multiple Regions of Nonthermal Quasi-Periodic Pulsations during the Impulsive Phase of a Solar Flare
Yingjie Luo, Bin Chen, Sijie Yu +2
Flare-associated quasiperiodic pulsations (QPPs) in radio and X-ray wavelengths, particularly those related to nonthermal electrons, contain important information about the energy…
The First Survey of Quiet Sun Features Observed in Hard X-Rays With NuSTAR
Sarah Paterson, Iain G. Hannah, Brian W. Grefenstette +5
We present the first survey of quiet Sun features observed in hard X-rays (HXRs), using the the Nuclear Spectroscopic Telescope ARray (NuSTAR), a HXR focusing optics telescope. The…
Detection of weak ubiquitous impulsive nonthermal emissions from the solar corona
Rohit Sharma, Divya Oberoi, Marina Battaglia +1
A ubiquitous presence of weak energy releases is one of the most promising hypotheses to explain coronal heating, referred to as the nanoflare hypothesis. The accelerated electrons…
The Lyman- Emission in a C1.4 Solar Flare Observed by the Extreme Ultraviolet Imager aboard Solar Orbiter
Ying Li, Qiao Li, De-Chao Song +7
The hydrogen Lyman- (H {\sc i} Ly) emission during solar flares has rarely been studied in spatially resolved images and its physical origin has not been fully understood. In…
Observations of Thomson scattering from a loop-prominence system
Juan Carlos Martínez Oliveros, Juan Camilo Guevara Gómez, Pascal Saint-Hilaire +2
We describe observations of the white-light structures in the low corona following the X8.2 flare SOL2017-09-10, as observed in full Stokes parameters by the Helioseismic and Magne…
Spatial distribution of jets in solar active regions
Jonas Odermatt, Krzysztof Barczynski, Louise K. Harra +2
Context. Solar active regions are known to have jets. These jets are associated with heating and the release of particles into the solar wind. Aim. Our aim is to understand the spa…
The Spectrometer Telescope for Imaging X-rays (STIX) on Solar Orbiter
Laura A. Hayes, Sophie Musset, Daniel M üller +1
The Spectrometer/Telescope for Imaging X-rays (STIX) is one of the 10 instruments on-board the scientific payload of ESA's Solar Orbiter mission. STIX provides hard X-ray imaging s…
The coupling of an EUV coronal wave and ion acceleration in a Fermi-LAT behind-the-limb solar flare
Melissa Pesce-Rollins, Nicola Omodei, Sam Krucker +6
We present the Fermi-LAT observations of the behind-the-limb (BTL) flare of July 17, 2021 and the joint detection of this flare by STIX onboard Solar Orbiter. The separation betwee…
On the faintest solar coronal hard X-rays observed with FOXSI
Juan Camilo Buitrago-Casas, Lindsay Glesener, Steven Christe +23
Solar nanoflares are small eruptive events releasing magnetic energy in the quiet corona. If nanoflares follow the same physics as their larger counterparts, they should emit hard…
Forward-fitting STIX visibilities
Anna Volpara, Paolo Massa, Emma Perracchione +6
Aima. To determine to what extent the problem of forward fitting visibilities measured by the Spectrometer/Telescope Imaging X-rays (STIX) on-board Solar Orbiter is more challengin…
Using Multiple Instance Learning for Explainable Solar Flare Prediction
Cédric Huwyler, Martin Melchior
In this work we leverage a weakly-labeled dataset of spectral data from NASAs IRIS satellite for the prediction of solar flares using the Multiple Instance Learning (MIL) paradigm.…
First hard X-ray imaging results by Solar Orbiter STIX
Paolo Massa, Andrea F. Battaglia, Anna Volpara +15
Context. The Spectrometer/Telescope for Imaging X-rays (STIX) is one of 6 remote sensing instruments on-board Solar Orbiter. It provides hard X-ray imaging spectroscopy of solar fl…
Multi-instrument STIX microflare study
J. Saqri, A. M. Veronig, A. Warmuth +7
During its commissioning phase in 2020, the Spectrometer/Telescope for Imaging X-rays (STIX) on board the Solar Orbiter spacecraft observed 69 microflares. The two most significant…
