Energy Evolution from the Chromosphere to the Heliosphere in the 2021 October 28 Solar Eruption
Katharine K. Reeves, Daniel B. Seaton, Cynthia Cattell +20
We perform a detailed study of the energetics for a well-observed solar eruption and flare that occurred on 28 October 2021. This event included a GOES class X1.0 flare, a global E…
Multi-Viewpoint Observation of a Failed Prominence Eruption on the Sun
Tingyu Gou, Katharine K. Reeves, Peter R. Young +5
Solar eruptions are sudden ejections of coronal mass and magnetic fields accompanied by intense energy release. The eruptive structure does not always erupt successfully, but somet…
Heating of a plasma sheet in nonequilibrium ionization with nonthermal electrons
Jin-Yi Lee, John C. Raymond, Katharine K. Reeves +4
A flux rope eruption on September 10, 2017 provides unique observations of the plasma sheet beneath the rising flux rope. The plasma sheet is likely in a nonequilibrium state in te…
Disentangling Thermal and Abundance Characteristics in a Solar Flare Using SDO/AIA, Hinode/XRT, and MinXSS-1 Observations
Xiaoyan Xie, Anna Chen, Crisel Suarez +5
We investigate the thermal properties of a solar flare by the observations of soft X-ray Telescope (XRT) on board Hinode and the Atmospheric Image Assembly on board the Solar Dynam…
Supra-arcade downflows in an extensive fan associated with a giant quiescent solar filament eruption
Xiaoyan Xie, Katharine Reeves, Chengcai Shen +6
We investigate the aftermath of a giant quiescent solar filament eruption on December 24, 2023. One feature of the eruption is an extensive fan above the filament channel that is a…
Spectroscopic Observations of Supra-Arcade Downflows
Ryan J. French, Maria D. Kazachenko, Teodora Mihailescu +1
Despite their somewhat-frequent appearance in EUV imaging of off-limb flares, the origins of Supra-Arcade Downflows (SADs) remain a mystery. Appearing as dark, tendril-like downflo…
