Non-thermal Sources from Stereoscopic Hard X-ray and Earth-based Microwave Observations in a Data-Constrained Magnetohydrodynamic Simulation
Keitarou Matsumoto, Satoshi Inoue, Meiqi Wang +5
We analyze the X7.1 flare on 2024 October 1 from NOAA AR 13842 using hard X-ray (HXR) imaging, microwave observations by the Expanded Owens Valley Solar Array (EOVSA), and a three-…
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…
Stereoscopic Observations of Solar X-ray Sources Explained by a Data-Constrained Magnetohydrodynamic Simulation
Keitarou Matsumoto, Satoshi Inoue, Meiqi Wang +6
We investigated the three-dimensional (3D) magnetic structures and dynamics responsible for particle acceleration in an X7.1-class flare that occurred on October 1, 2024, in NOAA a…
Spectral component imaging of solar X-ray flares
Muriel Zoë Stiefel, Paolo Massa, Alessia Guidetti +2
Solar hard X-ray observations provide diagnostics of the hottest plasmas and of nonthermal electron populations present during solar flares and coronal mass ejections. HXR images o…
Superhot (> 30 MK) flare observations with STIX: Joint spectral fitting
Muriel Zoë Stiefel, Natália Bajnoková, Säm Krucker
Spectroscopic analysis of large flares (>X1) in the hard X-ray (HXR) range offers unique insights into the hottest (> 30 MK) flare plasma, the so-called superhot thermal component.…
Near-continuous tracking of solar active region NOAA 13664 over three solar rotations
I. Kontogiannis, Y. Zhu, K. Barczynski +6
Magnetic flux emergence and decay in the Sun span from days to months. However, their tracking is typically limited to about half a solar rotation when relying on single-vantage-po…
