We present a kinematic study of the Herbig-Haro objects HH 202, 203 and 204\nusing Halpha and [NII] Fabry-Perot velocity maps. For HH 202 we find new\nfeatures that could belong to this HH object or that perhaps are associated\nwith an outflow different from HH 202. Because of its high velocity (up to 100\nkm/seg) this outflow probably can be a HH flow not catalogued previously. Large\ninternal motions are found in the fainter regions of HH 203-204, as well as\nevidence of transverse density gradients. We show that the apex of HH 204 is\nthe zone of maximum velocity in agreement with bow shock models. From our\nstudies, we find kinematic evidence that suggests that HH 203-204 and HH 202\nare part of a single and large (approx 0.55 pc) HH flow.\n
