  In frame of an implementation of the cooperative program studying of
asteroids between the Kharadze Abastumani Astrophysical Observatory and the
Astronomical Institute of V.N. Karazin Kharkiv National University the
observations for five main-belt asteroids were performed to obtain their
magnitude-phase relations and other physical characteristics. Preliminary
results of the photometrical observations for the large dark asteroid (1390)
Abastumani are presented.
