Proper Motion of a Galaxy
Here is a paper about an observation of a water maser in IC10 (a small local group galaxy) using VLBI that has determined the proper motion of that galaxy (relative to some background quasars). The observations over four years have given numbers suggesting that the galaxy is gravitationally bound to M31, and that M31 has a mass or 7.5x1011 Solar masses.
