Time series showing the decay of an OPU in AR 11967. The individual columns show the observables of the OPU at different times, from 19:00 UT on 4 February 2014 to 10:40 UT on 5 February 2014. From top to bottom:I_c, B, B_LOS, γ, and v_LOS. All panels have a FOV of $22\stackrel{″}{.}4\times 22\stackrel{″}{.}4$ and the red contours indicate the orphan penumbra and its remains. We show the magnetic field and the velocity at τ = 1. The red arrows in the top row point towards disk centre. The purple arrows in the third column mark the leftover magnetic flux concentration.
