Evolution of the inverted-Y-shaped jet with QSEBs at its footpoints. Panel (a) shows the two QSEBs in the Hβ wing. The yellow arrow points to the limb direction. Panel (b) shows the footpoints of the inverted-Y-shaped structure marked as Strand 1 and 2. Strand 1 originates close to QSEB-B and is shown in panels (b) and (c). Strand 2 starts later from the location of QSEB-A and is shown in panel (c) when it merges with Strand 1. Panel (d) shows the spire of the jet-like top part of the inverted-Y-shaped jet. Panel (e) points to the brightening in the core of the Hβ line, which occurs just below the point of intersection of the two strands, while panel (f) points to a brightening at the base of this structure. Note that the wavelength positions are different in the panels, to best show the inverted-Y-shaped jet at different instances. The QSEBs are shown only in panels (a) and (b) due to their clear visibility in the wing positions, and they fade before the jet itself dissipates. They are marked in panel (a). The full evolution of the inverted-Y-shaped jet can be viewed in the online movie.
