Sunspot and magnetic flux decay: what are we missing?
The sunspots structure, evolution and the role that they play in the evolution of the solar magnetic field are still open questions. We present a wide vision about these issues from several points of view. We firstly show the last observational evidences about a relation between the sunspot penumbra, the moat, the MMFs and their role in the decay of sunspots. Later, we explain why these important aspects are not enough for understanding the decay (and dissapearance) of the magnetic flux of the Active Region. We show how we have attacked this question using MDI and TRACE data.
