Field line connectivities obtained through the NLFFF extrapolation. Top panel: the green and red field line sets illustrate the general connectivity between the main polarities of AR11106 and resemble structures visible in the SDO/AIA image of Fig. 1. The yellow field lines are traced from the region at the base of the jet and clearly reproduce the geometry of the latter. Lower panels: local and remote connectivities of the region around the minor positive polarity p3. One of the field line sets is colored according to the value of B_z, the colorscale follows the color bar on the left. The ivory and royal-blue field line sets show twisted flux ropes on either side of the central spine.
