Overview of the observed region in Hβ blue wing (top) and SJI 1400 (bottom). The white rectangle marks the region used for studying the QSEBs and UV brightenings. Red contours in the top panel denote the QSEB detections. The dark elongated thread-like features are spicules. Inside Region 1, a spicule is visible close to the QSEB, shown by a white arrow, which later becomes part of an inverted-Y-shaped jet as discussed in Sect. 4.1. Yellow contours in the bottom panel represent the detected > 5σ UV brightenings. The yellow arrow in the top panel shows the direction towards the north limb.
