The results of a photographic plate search for stars as faint as V=16 which may be occulted by Pluto or Charon between 1 January 1990 and 31 December 1999 are presented. Circumstances for the closest approach of Pluto to 32 stars and Charon to 28 stars are presented. UBVRI photometry is given for some of the brightest stars found in a search of the Space Telescope Guide Star Catalog for Pluto occultations. Finding charts are provided for some of the best events. The brightest star (V=12.7) may be occulted by both Pluto and Charon on 26 September 1999.
