We present the analysis of an eruptive event that took place on the eastern limb on April 21, 2015, which was observed by the Ondrejov horizontal telescope and spectrograph. The eruption of the highly twisted prominence was followed by the onset of soft X-ray sources. We identified the structures observed in Ha spectra with the details on the Ha filtergrams and analyzed the evolution of Doppler component velocities. The timing and observed characteristics of the eruption were compared with the prediction of the model based on the twisting of the flux ropes and the kink/torus instability.
