| Abstract: |
We make a comparison between small scale chromospheric brightenings
and energy release processes through examining the temporal evolution
of sequential chromospheric brightenings (SCBs), derive propagation
velocities, and propose a connection of the small-scale features to
solar flares. Our automated routine detects and distinguishes three
separate types of brightening regularly observed in the chromosphere:
plage, flare ribbon, and point brightenings. By studying their
distinct dynamics, we separate out the flare-associated bright points
commonly known as SCBs and identify a propagating Moreton
wave. Superimposing our detections on complementary off-band images,
we extract a Doppler velocity measurement beneath the point
brightening locations. Using these dynamic measurements, we put
forward a connection between point brightenings, the erupting flare,
and overarching magnetic loops. A destabilization of the pre-flare
loop topology by the erupting flare directly leads to the SCBs
observed. |
