Temporal evolution of Jet 1. Columns 1 to 4 show AIA 304 Å and 193 Å, SJ 1330 Å and 1400 Å, and HMI magnetogram images, respectively. Time evolves from 17:24 UT (first row) to 17:29 UT (last row). The arrows in panels 1-d, 2-d and 3-d indicate the location of the loop and the jet under study. In panels 4-a to 4-f, the red and blue contours indicate regions with strengths of –20 G and 20 G, respectively. The white arrow in panel 1-a shows the position of the mini-filament (see text for more details) and the corresponding green arrow in panel 4-a indicates the underlying polarity inversion line.
