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…
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…
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…
Thermospheric Density, Composition, and Temperature from GOES-R/SUVI Solar Occultations
Robert H. A. Sewell, Edward M. B. Thiemann, Jocelyn Lafyatis +6
A new dataset of atomic oxygen and molecular nitrogen number density profiles, along with thermospheric temperature profiles between 180 and 500 km, has been developed. These profi…
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…
CATEcor: an Open Science, Shaded-Truss, Externally-Occulted Coronagraph
Craig E. DeForest, Daniel B. Seaton, Amir Caspi +7
We present the design of a portable coronagraph, CATEcor, that incorporates a novel "shaded truss" style of external occultation and serves as a proof-of-concept for that family of…
Observations of the Polarized Solar Corona during the Annular Eclipse of October 14, 2023
Daniel B. Seaton, Amir Caspi, Nathalia Alzate +10
We present results of a dual eclipse expedition to observe the solar corona from two sites during the annular solar eclipse of 2023 October 14, using a novel coronagraph designed t…
A Chromatic Treatment of Linear Polarization in the Solar Corona at the 2023 Total Solar Eclipse
Ritesh Patel, Daniel B. Seaton, Amir Caspi +17
The broadband solar K-corona is linearly polarized due to Thomson scattering. Various strategies have been used to represent coronal polarization. Here, we present a new way to vis…
