When Magnetic Field Lines Stretch, Snap, and Expand: A New Look at Solar Flares with L-maps
Maria D. Kazachenko, Yuhong Fan, Andrey N. Afanasyev
Understanding the three-dimensional evolution of coronal magnetic fields during solar flares remains challenging due to the lack of direct coronal field measurements. Here we combi…

A data-driven MHD simulation of the 2011-02-15 coronal mass ejection from Active Region NOAA 11158
Yuhong Fan, Maria D. Kazachenko, Andrey N. Afanasyev +1
We present a boundary data-driven magneto-hydrodynamic (MHD) simulation of the 2011-02-15 coronal mass ejection (CME) event of Active Region (AR) NOAA 11158. The simulation is driv…

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…
