## [22.13] The Proper Motion of 4C 39.25

A. L. Fey (USNO), T. M. Eubanks (USNO), K. A. Kingham (USNO)

The radio source 4C 39.25 exhibited significant proper motion during the period 1986--1997 as observed by astrometric and geodetic Very Long Baseline Interferometry (VLBI). The observed astrometric proper motion for this source agrees well with the superluminal motion of the brightest component found in VLBI images. There is also good evidence that this component has been decelerating at a rate of \sim13.6 \muas yr^-2 since at least 1986.
