Observations of a Faint Nonthermal Onset before a GOES C-class Flare
Natália Bajnoková, Iain G. Hannah, Hannah Collier +6
We present analysis of a GOES C1-class flare from 2022 September 6, which was jointly observed as occulted by Nuclear Spectroscopic Telescope ARray (NuSTAR) and on-disk by Spectrom…
Measuring the Magnetic Field of a Coronal Mass Ejection from Low to Middle Corona
Xingyao Chen, Bin Chen, Sijie Yu +44
A major challenge in understanding the initiation and evolution of coronal mass ejections (CMEs) is measuring the magnetic field of the magnetic flux ropes (MFRs) that drive CMEs.…
Solar Orbiter's 2024 Major Flare Campaigns: An Overview
Daniel F. Ryan, Laura A. Hayes, Hannah Collier +17
Solar Orbiter conducted a series of flare-optimised observing campaigns in 2024 utilising the Major Flare Solar Orbiter Observing Plan (SOOP). Dedicated observations were performed…
Multispacecraft Observations of the 2024 September 9 Backside Solar Eruption that Resulted in a Sustained Gamma Ray Emission Event
Nat Gopalswamy, Pertti Mäkelä, Sachiko Akiyama +6
We report on the 2024 September 9 sustained gamma ray emission (SGRE) event observed by the Large Area Telescope (LAT) onboard the Fermi satellite. The event was associated with a…
Highly Polarized Type III Storm Observed with Parker Solar Probe
Marc Pulupa, Stuart D. Bale, Immanuel Christopher Jebaraj +2
The Parker Solar Probe (PSP) spacecraft observed a large coronal mass ejection (CME) on 5 September 2022, shortly before closest approach during the 13th PSP solar encounter. For s…
Study of Particle Acceleration using Fine Structures and Oscillations in Microwaves from Electron Cyclotron Maser
Rohit Sharma, Marina Battaglia, Sijie Yu +3
The accelerated electrons during solar flares produce radio bursts and nonthermal X-ray signatures. The quasi-periodic pulsations (QPPs) and fine structures in spatial-spectral-tem…
