Abstract Our program was based on simultaneous observations of the same solar region with the Universal Birefringent Filter (UBF) at the Vacuum Tower Telescope (VTT) and with the Big Dome BD Universal Spectrograph (USG). For the UBF images analysis we refer to the 13 June 1980 RG 2502/2511 (N12-E11) observations. Selected pictures present the line profiles for Hα, Hβ, Mg-b 1 and Na-D 2 at some interesting “pixels” of the analyzed AR. We present the detailed photometric morphology of the observed active area and the longitudinal velocity field pattern. A comparison with the corresponding UVSP data is given.
