Multiline Spectropolarimetric Evidence for Photospheric Reconnection in Ellerman Bombs from DKIST

Rahul Yadav, Maria D. Kazachenko, Viggo Hansteen

Ellerman bombs (EBs) are compact, transient brightenings observed in the wings of Balmer lines and are believed to result from magnetic reconnection in the lower solar atmosphere.…

Evolution of Flare Ribbon Bead-like Structures in a Solar Flare

Ryan J. French, Maria D. Kazachenko, David Berghmans +6

We present fast cadence and high resolution observations of flare ribbons from the Solar Orbiter Extreme Ultraviolet Imager (EUI). Utilizing the short-exposure observations from th…

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 wit…

Photospheric Pore Rotation Associated with a C-class Flare from Spectropolarimetric Observations with DKIST

Rahul Yadav, Maria D. Kazachenko, Andrey N. Afanasyev +2

We present high-resolution observations of a C4.1-class solar flare (SOL2023-05-03T20:53) in AR 13293 from the ViSP and VBI instruments at the DKIST. The fast cadence, good resolut…

Simultaneous spectropolarimetric observations in the H and Ca II 8662 Å lines of an active region

Harsh Mathur, K. Nagaraju, Rahul Yadav +1

We present spectropolarimetric observations of an active region recorded simultaneously in the H Ca II 8662 Å lines. The sunspot exhibits multiple structures, including a lightb…

Solar Atmospheric Heating Due to Small-scale Events in an Emerging Flux Region

Rahul Yadav, Maria D. Kazachenko, Andrey N. Afanasyev +2

We investigate the thermal, kinematic and magnetic structure of small-scale heating events in an emerging flux region (EFR). We use high-resolution multi-line observations (includi…
