Examples of QSEBs in the Hβ wing and their associated UV brightenings in the aligned SJI 1400. The QSEBs are outlined with red contours in the top-left panel. The 5σ brightenings are marked with yellow contours in the SJI 1400 panel (bottom left). The colored boxes in the left panels are shown at a higher magnification in the right columns, which display both the QSEBs and the UV brightenings. The zoomed-in boxes of SJI 1400 also show the red contours of the QSEBs near the UV brightenings. The yellow diagonal lines over the SJI mark the area that is covered by the IRIS spectrograph raster. The direction of the solar limb is shown by the yellow arrow in the Hβ wing image.
