Abstract
We describe the results of three-epoch intercontinental VLBI observations of the 22 GHz H2O masers near the compact HII region W3(OH). We have determined the relative proper motions of individual maser components. Assuming a distance to the source of 2.2 kpc, we are able to obtain a full 3-dimensional description of the kinematics of the emitting region, which indicates that the H2O masers are part of bipolar outflow.
