report:

We observed the GRB 030329 afterglow (Peterson and Price, GCN 1985) with
1.5-m Russian-Turkish Telescope RTT150 at Bakyrlytepe (TUBITAK National
Observatory, Turkey). The observations started at Mar 31.724 UT.

OT magnitude in all BVRI Bessel filters was constant during first 1.5 hours
of our observation. We measured R=16.91 for the OT, assuming that magnitude
of "A" star is R=16.20.
