Description: 
   A photographic search was conducted for stars that may be occulted
   by the unusual solar system object (2060) Chiron during the period
   from fall 1993 through summer 1996. 44 candidates were identified
   to a limiting V magnitude of 16, and for which the minimum appulse
   separation with Chiron is predicted to be less than 2.5arcsec.
