A new photograph and some spectra have been obtained for the group of HH objects HH 52, 53, 54. A long, gaseous streamer extends from HH 54 and produces an appearance very similar to that of HH 12. The spectra provide some additional radial velocities and line-intensity measurements for the group. It is confirmed that HH 54D is a star with no unusual photometric or spectroscopic characteristics. Attention is drawn to the distance of 400 pc derived by FitzGerald (1974, 1976) for a globule in the Cha II cloud, and it is suggested that the whole complex of gas, dust, and stars may well be further away than the 140 pc generally assumed. The spatial and velocity characteristics of this group of HH objects are discussed. The data do not support the identifications proposed by Sandell et al. (1987) as sources for the observed flows.
