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:
