We continue to monitor the OT of GRB030329.
Observations were made on April 8, 9, 10, 2003 in R and I (Johnson)
spectral band with the 70-cm and 38-cm Cassegrain telescopes of CrAO. Based
on filed photometry by A. Henden (GCN 2023) we estimate the OT magnitude as
following
Mid time, UT telescope exposure mag err
Apr.08.9284 K-380 20x300s R 19.35 0.25
Apr.09.9179 AZT-8 8x150s R 19.56 0.19
