Asfandiyarov, B.B. Kahharov (UBAI), A.Pozanenko (IKI), V.Rumyantsev (CrAO), G.Beskin (SAO) on behalf of large collaboration report: We have observed the OT of GRB030328 (Peterson and Price, GCN 1974) on Mar.29 with 1.5m telescope of Mt.Maidanak High-altitude Observatory (UBAI). Using star "A" as a reference (GCN 1975) and photometry by A.Henden (GCN 2114) we estimate the OT magnitudes: Mid time (UT) Mar.29 exposure filter mag err 18:00 5x300 B 22.77 0.43 18:48 5x300 R 22.10 0.28 Obtained R-magnitude is consistent with the measurement by P. Garnavich et al. (GCN 2036). This message may be cited.
