On 27 February 2007, Hinode SOT/SP acquired a time series of full-Stokes spectra of a regular, medium-sized sunspot NOAA 10944 located near the center of the solar disk. The inversion code SIR (Ruiz Cobo and del Toro Iniesta 1992, ApJ 398, 375) was applied to these data and a 3-h long time series of 34 spatial 3D maps of plasma parameters in the umbra and penumbra were computed. The temporal and spatial resolutions are 5.5 min and 0 :0032, respectively. A simultaneous series of SOT/BFI G-band images was utilized for complementary measurements of horizontal motions and sizes of small-scale features.
