(Received 31 August 2001 / Accepted 24 October 2001)

We performed morphological and spectro-imaging investigations of the little-studied HH object Haro 6-19 (HH319). Besides the main object, two other small HH knots were found. The images of the object in various spectral lines and maps of radial velocity and electronic density are presented. Either of the T Tauri stars FY and FZ Tau is suggested as the possible exciting source. The spatial distribution of the density and radial velocity in the object, combined with other evidence, shows that HH319 could be a shocked cloudlet. In many aspects HH319 is similar to HH29 in L1551.

Key words: ISM: individual objects: HH319 -- Herbig-Haro objects -- ISM: kinematics and dynamics
