The predictions are basedon a computerized comparison of the occulting bodies' ephemerides andnine major star catalogs. The search is complete for all numberedasteroids whose angular diameters exceed 0.08 arcsec during the searchyears. Preliminary ground tracks are shown for the more favorableoccultations.
