TL;DR: In this article, a linear force-free field extrapolation of one of the magnetograms was performed to study the magnetic topology of small-scale EBs and their possible role in the flux emergence process, and it was found that 23 out of 47 EBs are cospatial with bald patches (BPs), while 15 are located at the footpoints of very flat separatrix field lines passing through distant BPs.

TL;DR: In this article, the authors investigate the statistical properties of Ellerman bombs in the dynamic emerging flux region NOAA Active Region 8844, underneath an expanding arch filament system, and find that Ellerman Bombs occur and recur in preferential locations in the low chromosphere, either above or in the absence of photospheric neutral magnetic lines.

TL;DR: In this article, a feature recognition system for the Solar Dynamics Observatory (SDO) is presented, which can detect, trace, and analyze numerous phenomena, including flares, sigmoids, filaments, coronal dimmings, polarity inversion lines, sunspots, X-ray bright points, active regions, CORonal holes, EIT waves, and coronal mass ejections (CMEs), coronal oscillations).

TL;DR: In this article, the authors present a code for automated detection, classification, and tracking of solar filaments in full-disk Hα images that can contribute to Living With a Star science investigations and space weather forecasting.

TL;DR: The Flare Genesis Experiment (FGE) as discussed by the authors was equipped with a vector polarimeter and a tunable Fabry-Perot narrow-band filter and recorded time series of filtergrams, vector magnetograms and Dopplergrams at the Ca'i 61222'A line.
