We study the presence of reversed polarity magnetic flux in sunspot penumbra.We applied a new regularized method to deconvolve spectropolarimetric dataobserved with the spectropolarimeter SP onboard Hinode. The new regularizationis based on a principal component decomposition of the Stokes profiles. Theresulting Stokes profiles were inverted to infer the magnetic field vectorusing SIR. We find, for the first time, reversed polarity fields at the borderof many bright penumbral filaments in the whole penumbra.
