Snapshot of images and spectra of QSEB – 2 at the instance of maximum Si IV 1394 Å emission, with the same format as Fig. 7. The QSEB is located at y = 124 (in IRIS pixels) at t = 08 : 53 : 29 UT. The spectral profiles of Mg II k 2796.39 Å, Mg II triplet 2798.8 Å, and Si IV 1394 Å are shown for the region covered by the slit at y = 125, which is at a spatial offset of one pixel from the location of QSEB and are in units of DN s⁻¹. An animation of this figure is available online.
