Observations of the magnetic fine structure of a facula.
Simultaneous spectropolarimetric observations of a facula have been carried out in 10 spectral lines with a spatial resolution of 1arcsec. Local variations of the magnetic field strength and the filling factor of fluxtubes were obtained. The analysis of the velocities inside fluxtubes shows that positive and negative Doppler shifts are present, at
