Description:
The astrometric measurements of the original 1981 UCAS survey plates were computed, leading to a grand total of 1252 orbits for newly discovered asteroids ranging in absolute magnitude from H = 10.5 to 19.5. New programs were created and existing computer routines were revised at Lowell Observatory, which has streamlined the process of correctly identifying asteroid images on archival photographic plates. The recovery and accurate measurements were made of 130 UCAS asteroids at other oppositions on plates taken by C. T. Kowal at Palomar Mountain in 1978 and 1979. When added to the 90 other UCAS objects identified by other investigators, this brings the total of multiple-opposition orbits to 220. Of the 56 UCAS asteroids known to be planet crossing, 11 were recovered at second oppositions. The recovery and accurate measurements of about 20 non-UCAS asteroids identified on the plates were examined.
