Spatial distribution of the 53 co-temporal UV brightenings around the QSEBs. Each QSEB is put at the center of the figure denoted by the shaded red circle. For each UV brightening, the colored markers are shown for all the overlapping instances of occurrence, and at distances and angles calculated with their respective QSEBs. Panel a distributes the UV brightenings based on the distance of their centroids from the QSEBs. Panel b distributes the UV brightenings based on the distance of their nearest boundaries from the QSEBs. The direction of the nearest solar limb is toward the north. Here, the x and y axis have units in IRIS pixels (1 pixel = 0$\stackrel{″}{.}$33).
