Scientific paper

We present the discovery of an optical counterpart of the extended bipolar CO outflow source observed by Sato and Fukui (1989) in L1251. Deep CCD images through forbidden S II, H-alpha and continuum filters reveal a number of knots of different physical nature in the main body of the object. Two emission-line knots are probably Herbig-Haro objects. We recognized a further knot outside the main body which is well defined in forbidden S II, much fainter in H-alpha and below the detection limit in the continuum. These emission line knots probably form a jet. We identified its driving source with IRAS 22343+7501 the supposed origin of the CO outflow.
