Quiet phase observations. The quiet or energy storage phase of the jet is shown in AIA 171 Å IRIS Si IV SJI, and in SST Hα observations. In the hot AIA channel (panel a), a quiet-phase jet spine is present at 08:03 UT (one hour before the main jet event). The circular brightening is evident in the transition region temperature observed with IRIS (panel b), and the dark absorbed structure of the swirled anemone is observed in the chromospheric Hα observations (panel c). The vertical dark line in the IRIS SJI is the position of the slit. The field of view for this figure is presented as a white rectangular box in Figs. 1b and c. This figure has an associated animation that shows the evolution of the region from 08:03 UT to 09:28 UT. Movies are available online.
