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…
A Hot Cusp-Shaped Confined Solar Flare
Aaron Hernandez-Perez, Yang Su, Julia K. Thalmann +5
We analyze a confined flare that developed a hot cusp-like structure high in the corona (H ~ 66 Mm). A growing cusp-shaped flare arcade is a typical feature in the standard model o…
Generation mechanisms of quasi-parallel and quasi-circular flare ribbons in a confined flare
Aaron Hernandez-Perez, Julia K. Thalmann, Astrid M. Veronig +3
We analyze a confined multiple-ribbon M2.1 flare (SOL2015-01-29T11:42) that originated from a fan-spine coronal magnetic field configuration, within active region NOAA 12268. The o…
Direct Observation of Two-Step Magnetic Reconnection in a Solar Flare
Tingyu Gou, Astrid M. Veronig, Ewan Dickson +2
We report observations of an eruptive X2.8 flare on 2013 May 13, which shows two distinct episodes of energy release in the impulsive phase. The first episode is characterized by t…
Measurements of electron anisotropy in solar flares using albedo with RHESSI X-ray data
Ewan Cameron Mackenzie Dickson, Eduard Kontar
The angular distribution of electrons accelerated in solar flares is a key parameter in the understanding of the acceleration and propagation mechanisms that occur there. However,…
