Scientific paper

Crossley and 120-in. direct plates obtained between 1946 and 1980 have been measured for the proper motions of the Herbig-Haro objects HH 1, HH 2, and HH 3, which were then referred to the motion of the Orion complex. HH 3 is found to be essentially stationary, while HH 1 and HH 2 have large cross motions in opposite directions, diverging from the position of a faint, red Orion association member which Cohen and Schwartz (1979) have proposed as the exciting star of HH 1. While most of the individual nuclei within each HH object are moving parallel to one another, there is a considerable dispersion in speeds: 155-351 km/sec for HH 1 and 100-294 km/sec for HH 2. A discrepancy is seen between absolute tangential velocities and the relative velocities of gas flowing into the shock front that are inferred from the optical spectra and shock model theory.
