Abstract
We present observations and preliminary results of H2O maser emissions in the circumstellar envelope of the evolved star W434K, obtained by the very large baseline array at the three epochs from 2003 to 2004 with time spacing between 2-3 months. By observing the masers with this time spacing, the change in position can be determined. Moreover, by determining the motion and estimating the maser shell thickness, we should be able to calculate the mass loss rate of the evolved star.
