Reconnection regions and rapid motion of photospheric magnetic fields close to the sunspot. In Hα blue wing (left panel) the reconnection sites are outlined with blue contours, where enhanced Hα wing emission mark the location of Ellerman Bombs. The intensity at these locations is 1.45 times the intensity of the reference quiet Sun spectrum. The middle panel shows the cotemporal and aligned PHI B_LOS map. Yellow circles mark the locations of these reconnection points. The right panel shows, at each pixel, the extremum of B_LOS over 1 h before the onset of the jet generated from the original PHI data. Red contours mark pixels that have |B_LOS|> 100 G for both polarities during the 1 h sequence.
