Making emphasis on observations that have included some type of polarization analysis, I concentrate on two subjects. First, the vector magnetic field configuration of structures with different sizes is reviewed. I cover from magnetic knots, and their relation to small scale magnetic elements, to large sunspots. In doing so, a different concept of

We present a color magnitude diagram (CMD) in the V and I bands reaching 4 magnitudes below the turn off (TO) and intermediate resolution spectra for 4 giant branch (GB) stars. The spectra allowed us to determine the cluster metallicity and radial velocity for the cluster Pal 1. The metallicity has been determined using the CaII triplet and other

We have performed numerical simulations of the rise of magnetic flux tubes through the convection zone. We find that the observed proper motions of pores and sunspots in young active regions can be understood as a consequence of the Coriolis force: conservation of angular momentum leads to a retardation of the rising flux loop with respect to those

Preliminary results of the inversion of spectropolarimetric maps of a sunspot observed with the Advanced Stokes Polarimeter (ASP) are presented. The method used, Stokes Inversion based on Response functions (SIR), does not assume constancy of the different parameters with depth, thus enabling us to embark on an analysis of the information at
