Dual-Perspective Microwave and Hard X-ray Constraints of Asymmetric Nonthermal Loops in an X-class Flare

Ruifei Huang, Yao Chen, Victor Melnikov +9

We report dual-perspective microwave and HXR observations of an X-class flare on 2024 May 15, taking advantage of the unique geometry of a front-side view from the Earth and a back…

Electron Acceleration and Plasma Heating in an Impulsive Confined C-class Solar Flare

I. N. Sharykin, I. V. Zimovets, G. V. Koynash +3

A detailed analysis of the impulsive C2.8 solar flare SOL2023-03-19T02:12 is presented, focusing on the microwave (MW) and X-ray domains. The flare was selected because of its impu…

On the possibility of using decayless kink oscillations of coronal loops to forecast powerful solar flares and coronal mass ejections

A. B. Nechaeva, I. V. Zimovets, I. N. Sharykin +1

This work investigates the decayless kink oscillations of solar coronal loops and examines possible changes in their behaviour in active regions (ARs) before powerful solar flares…

Magneto-Thermal Coupling and Coronal Heating in Solar Active Regions Inferred from Microwave Observations

Alexey A. Kuznetsov, Gregory D. Fleishman, Gelu M. Nita +1

The solar corona is much hotter than the photosphere and chromosphere, but the physical mechanism responsible for heating the coronal plasma remains unidentified yet. The thermal m…

Electron acceleration and transport in the 2023-03-06 solar flare

Alexey Kuznetsov, Zhao Wu, Sergey Anfinogentov +2

We investigated in detail the M5.8 class solar flare that occurred on 2023-03-06. This flare was one of the first strong flares observed by the Siberian Radioheliograph in the micr…

A Multi-Peak Solar Flare with a High Turnover Frequency of The Gyrosynchrotron Spectra from the Loop-Top Source

Zhao Wu, Alexey Kuznetsov, Sergey Anfinogentov +8

The origin of multiple peaks in lightcurves of various wavelengths remains illusive during flares. Here we discuss the flare of SOL2023-05-09T03:54M6.5 with six flux peaks as recor…
