   CERES  software  package  makes  available the basic ephemeris data
connected  not  only  with  minor  planets (MP)  but  comets and major
planets  for any  astronomer. One  can store  and  manage  various  MP
data  and  observatories  coordinates  within  the internal databases,
calculate   for  any  moment  MP   coordinates  and  their  first  two
derivatives  referred  to  various  planes  and  centers, visualize MP
tracks on the selected sky area  against  a stars background, simulate
MP  orbital  motion.
   New  additional  facilities  are elaborated. Now a user  can import
any  star  catalog  for  using  in  CERES  package,  calculate  global
and  topocentric  ephemerides  for MP  occultations of stars, generate
a list of  numbered and  unnumbered minor  planets visible in selected
sky region for any moment. These  options  can  help  any  observer in
controlling  the  quality  of  his  own  photo, CCD or photoelectrical
occultation observations before publishing  and in  searching  the new
objects on the sky.  With  the identification and  orbit determination
options which are now elaborating CERES software package may be useful
in monitoring of solar system objects including near Earth asteroids.
