Scientific paper

The spectra of the MnI 539.47 nm line of preceding sunspot of the NOAA 9563 active region and the quiet photosphere in the vicinity of this active region were observed. The observations were carried out with the horizontal solar spectrograph of Heliophysical Observatory in Debrecen on August 6, 2001. The profiles of the MnI 539.47 nm line in the quite photosphere, umbra and in four positions in penumbra, as well as their parameters (equivalent width (EW), central depth (CD) and full width at half maximum (FWHM)) are determined. Relative large increase (30-70%) of the MnI 539.47 nm line profile parameters from quiet photosphere to umbra is obtained. The MnI 539.47 nm line profile parameters observed in a sunspot exhibit an opposite behaviour to those observed in solar plages.
