Abstract. The L1634 bright-rimmed globule contains an intriguing arrangement of shock structures: two series of aligned
molecular shock waves associated with the Herbig-Haro flows HH 240 and HH 241. We present near-infrared spectroscopy
and narrow-band imaging in the (1,0) S(1) and (2,1) S(1) emission lines of molecular hydrogen. These observations yield the
spatial distributions of both the molecular excitation and velocity, which demonstrate distinct properties for the individual bow
