High resolution observations of a sunspot region were obtained on October 3, 1994 with the Multichannel Subtractive Double Pass (MSDP) spectrograph. This instrument installed at the focus of the Vacuum Tower Telescope (VTT) at Tenerife (Canary Islands) operated in the Hα line. Intensity fluctuations and Doppler shift velocities at several wavelengths were derived over a two dimensional field of...

The magnetic, thermal and velocity structure of a regular sunspot, observed close to solar disk center is presented. Spectropolarimetric data obtained with the Tenerife Infrared Polarimeter (TIP) in two infrared Fe I lines at 15 648.5 Å and 15 652.8 Å are inverted employing a technique based on response functions to retrieve the atmospheric stratification at every point in the sunspot. In order...
