There are the first in the world observation of optical emission of GRB 050824 and GRB 060926 gamma-ray bursts. Our data combined with more later one gives the low of brightness drop t^-0.55+/-0.05^ for GRB 050824. We discovered optical flare for GRB 060926 around 500-700s. The power low spectral index (F_E_~E^-beta^) is equal beta=1.0+/-0.2. In the course of sky survey we have images of more than 90% possible sky. The virtual data-base and pipe-line was made. The limit to the orphan optical bursts rate is presented. We discovered 3 supernovae stars, they are the following: SN 2005bv (Ia-type) is the first one, opened from Russian territory, SN 2005ee is one of the most powerful among II-type supernovae, SN 2006ak (Ia-type). New method of the OT search after IPN-triangulation gamma-observation is proposed and tested.
