a)B_z component of the magnetic field at the mid-photosphere (z = 0.9 Mm), with the velocity field overplotted at t = 243 min and b)t = 286 min. c) Fieldlines traced around the center of the EFR at t = 243 min, showing the arcade. Overplotted is the full magnetic field vector colored by the B_z component of the field at z = 0.9 Mm. Red is positive and blue is negative. The red rectangular inset marks the same region as the one in b). d) Fieldlines at t = 286 min, showing the deformation of the PIL. e) Isosurface of V_z> 60 km s^-1 showing the V-shaped jet at t = 248 min. f) The emission of several jets at t = 286 min (isosurface of V_z> 60 km s^-1).
