Scientific paper

Brightening in the chromosphere comes in three different flavors: plage, flare ribbon, and point. These types of brightening are all characterized by intensity above the background but have different dynamics causing the increased intensity. We have developed an automated software suite to identify and track both ribbon and point brightening associated with moderate sized flares observed in H alpha. Superposing our detections on complementary datasets, we produce a three-dimensional velocity map of flare ribbons, and a Doppler velocity measurement beneath the point brightening detections. These dynamic measurements allow us to postulate a physical connection between point brightening, the erupting flare, and coronal loops.
