We investigate the system of filaments in active region using observations of several spectral lines (H-alpha, H-beta and Cr1). Observations were made at VTT at Tenerife with high spatial an spectral resolution. More than 20 series of 2D spectra were recorded during one hour of observations. Data reduction is now made with aim to determine the time development of dynamics/oscillations in different filaments and different heights of solar atmosphere.
