Improving Solar EUV Irradiance Modeling with Differential Emission Measure Informed Spectra
Courtney L. Peck, Shah M. Bahauddin, Daniel B. Seaton +3
Solar extreme ultraviolet (EUV) irradiance predominantly originates from the chromosphere and corona, and variations in EUV irradiance are a significant driver of space weather at…
Polarimeter to Unify the Corona and Heliosphere (PUNCH)
Craig E. DeForest, Sarah E. Gibson, Ronnie Killough +74
The Polarimeter to Unify the Corona and Heliosphere (PUNCH) mission is a NASA Small Explorer to determine the cross-scale processes that unify the solar corona and heliosphere. PUN…
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…
Dynamics of Reconnection Nanojets in Eruptive and Confined Solar Flares
Annu Bura, Arpit Kumar Shrivastav, Ritesh Patel +6
Recent observations reveal small-scale reconnection-driven plasma ejections, often termed nanojets, triggered by magnetic field interactions at slight misalignment angles. These fa…
Evidence of Extreme Ultraviolet Resonant Excitation in the Middle Corona During A Solar Flare
Daniel B. Seaton, Cooper Downs, Giulio Del Zanna +10
We present observations of an eruptive solar flare on 2016 January 6 that occurred behind the solar limb from the perspective of the Earth, but was well observed by STEREO and the…
