\maketitle

The U.S. Naval Observatory has a long history of transit circle
observations of Solar system objects, mostly used to determine the
equator and equinox corrections for the various absolute star
catalogs. Work on the W1J00 catalog (1977-1982) and the current
pole-to-pole observing program (simultaneous observations from both
the Northern and Southern hemispheres) have allowed further
investigations of problems, improvements, and new techniques. For
example, daytime observations of Mars during the pole-to-pole program
should allow for a better determination of the night-minus-day
correction. The instrument in the Southern hemisphere is able to
observer stars to 5.1 magnitude in the daytime, allowing for a daytime
determination of the clock correction and the azimuth.
Improvements have also been made in the way the equator and equinox
corrections are being determined. These improvements while affecting
the most recent catalog reductions will also contribute to the
formation of the future Washington Fundamental Catalog.
