## Abstract We present projected rotational velocity measurements of the red giant in the symbiotic star MWC 560, using the highβresolution spectroscopic observations with the FEROS spectrograph. We find that the projected rotational velocity of the red giant is __v__ sin __i__ = 8.2 Β± 1.5 km s^β1^
