We have observed the OT found by Peterson and Price (GCN 1985) of GRB030329
with 1.5m telescope of High-altitude Observatory at Mt.Maidanak. Several
BVRI Bessel images were obtained on April, 3. Based on star filed photometry
by A. Henden (GCN 2023) we refined the estimation reported in GCN 2084 and
report new measurements:
