摘要：
We present results from polarimetric data on sunspot penumbrae obtained with the Vacuum Tower Telescope at the Observatorio del Teide, Tenerife, using the 'Gottingen' Fabry-Perot Interferometer. Speckle image reconstruction has been performed giving us a spatial resolution of 0.6". The observations were taken in the Fe 11 6149.2 angstrom line which, given its particular Zeeman splitting, has no instrumental (Q, U) to V crosstalk and provides us measurements of 1 and V Stokes profiles to analyse velocities and magnetic fields in penumbrae.
