report:

We continue observations of the GRB 030329 optical afterglow (Peterson
and Price, GCN 1985) with 1.5-m Russian-Turkish Telescope RTT150
at TUG in the Bessel BVRI-bands. 

We obtained 70 exposures at 06 Apr. 18:33UT - 07 Apr. 01:23UT;
and 48 exposures at 07.Apr 17:55UT - 08 Apr. 01:02UT
Second night observations were made under bad weather conditions.
The magnitudes obtained are as follows:

   UT          R      Rerr  		
Apr. 6.79    18.75   0.02
Apr. 6.83    18.76   0.02
Apr. 6.87    18.71   0.02

Apr. 7.97    18.91   0.03
Apr. 8.01    18.83   0.03   

There are no significant changes in the fluxes during two 
observational set in all BVRI-bands.
