Spectroscopic analysis and RHD modeling of the first Ca II H and H-epsilon flare spectra from DKIST/ViSP
Cole Tamburri, Adam Kowalski, Gianna Cauzzi +7
We analyze decay phase observations of the GOES class C6.7 flare SOL2022-08-19T20:31 by the Visible Spectropolarimeter (ViSP) on the National Science Foundation's Daniel K. Inouye…
Citizen CATE 2024: Extending Totality During the 8 April 2024 Total Solar Eclipse with a Distributed Network of Community Participants
Sarah A. Kovac, Amir Caspi, Daniel B. Seaton +240
The Citizen CATE 2024 next-generation experiment placed 43 identical telescope and camera setups along the path of totality during the total solar eclipse (TSE) on 8 April 2024 to…
Ubiquitous high-frequency waves and disturbances in the active region corona observed with DKIST/Cryo-NIRSP
Momchil E. Molnar, Richard Morton, Alin Paraschiv +4
The plasma of the solar corona harbors a multitude of coronal wave modes, some of which could be dissipated to provide the required energy and momentum to heat the corona and accel…
Atmospheric Gravity Waves Modulated by the Magnetic Field Configuration
Oana Vesa, Julio Morales, Jason Jackiewicz +2
Atmospheric gravity waves (AGWs) are buoyancy-driven waves excited by turbulent convection and contribute to the dynamics and energy transport of the lower solar atmosphere. We pre…
Unveiling Unprecedented Fine Structure in Coronal Flare Loops with the DKIST
Cole A. Tamburri, Maria D. Kazachenko, Gianna Cauzzi +8
We present the highest-resolution H observations of a solar flare to date, collected during the decay phase of an X1.3-class flare on 8 August 2024 at 20:12 UT. Observations wi…
The striated solar photosphere observed at 0."03, resolution
D. Kuridze, F. Wöger, H. Uitenbroek +5
Striated granular edges observed in the solar photosphere represent one of the smallest-scale phenomena on the Sun. They arise from the interaction of strongly coupled hydrodynamic…
