Proper motions of HH 222. Tangential motions of individual features are indicated by red arrows, which vary around a mean of 107 ± 25 km s −1; arrows show the expected motion in 300 yr. The black arrow shows the physical displacement that would take place in 300 yr assuming a motion of 100 km s −1. The dashed blue line indicates the direction to V380 Ori.
