Overview of the observed region in the Hβ blue wing, SJI 1400, and magnetic field (B_LOS). The two white squares mark the regions with continuous QSEB and UV brightening activity. The first four events analysed in this paper occurred in Region 1, and the fifth event occurred in Region 2. Red contours at the top outline the QSEB detections. Yellow contours outline > 5σ UV brightenings. The arrow in the top panel shows the direction towards the nearest limb. B_LOS maps with contours at 2σ above the noise level for these two regions are shown on the right, with the QSEB and UV brightening contours. The values for B_LOS in panels (c) and (d) have been saturated to ±100 G for better representation.
