Description: The proposed coordinated observations aim at understanding the intrinsic nature of moving magnetic features (MMFs) in the periphery of sunspots, trying to discriminate a few possibilities on their origin: 1) They are a part of magnetic flux of sunspots and representing sunspot decay
2) They are propagating kinks or knots in the magnetic lines of force of sunspots
3) They are manifestations of some type of flux emergence in sunspot outer edges
4) They are submerged magnetic flux caused by mass loading or dragged by convection. We plan the joint observations with BBSO/NST, Hinode and IRIS. Our proposal to NST has been already accepted and arranged in the interval of August 25-31.
