ABSTRACT.  The U.S. Naval Observatory 20-cm FASTT telescope is
making CCD observations of planets and asteroids directly tied
into the extragalactic J2000 radio reference system from ancilliary
observation of radio reference objects.  Objects as faint as V ~ 17.5
mag are routinely observed with the FASTT, and the estimated accuracy 
of these observations is +/-150 mas in each coordinate.  Once the 
Hipparcos/TYCHO catalogs become available in a few years, these and 
future FASTT positions can be improved to an accuracy of ~+/- 50 mas.  
Included in the current observing program are observations of the 
outer planets and of faint asteroids targeted for either spacecraft 
encounter or stellar occultations.
