report:

We continue observations of the GRB 030329 optical afterglow (Peterson
and Price, GCN 1985) with 1.5-m Russian-Turkish Telescope RTT150
at Bakyrlytepe. Assuming that star "A" has R=16.20 we have measured
the following magnitudes:

t-t0,hours       UT       R

54.3     March 31.75     16.91
55.2           31.78     16.92
57.1           31.86     16.99

We see the beginning of new phase of fading of the optical afterglow.
