Imaging spectropolarimetry with IBIS: evolution of a magnetic feature.

We present the results from observations of the solar atmosphere acquired at the Dunn Solar Telescope with the Interferometric Bidimensional Spectrometer (IBIS). Full Stokes profiles in the FeI 617.3 line and Stokes I in the CaII 854.2 were acquired with high spatial and spectral resolutions for more than one hour allowing us to study the evolution of a magnetic feature associated to AR11005. Here we search for possible correlations between photospheric and chromospheric events examining the magnetic flux density evolution and waves propagation in the solar atmosphere.
