V.Rumyantsev, E.Pavlenko, O.Antoniuk (CrAO) and A.Pozanenko (IKI) report:
We continue to monitor the OT of GRB030329 (GCN 2025).
The OT found by Peterson and Price (GCN 1985) is clearly visible in our
image taken
with Cassegrain 38-cm telescope of CrAO.Several 180 sec. exposures of R
(Johnson) filter were obtained. Based on filed photometry by A. Henden (GCN
2023) we estimate the OT magnitude as
Mid Time (UT) exposure OT
March, 30 17:56:25 1x180 s R = 16.61
The figure image can be found in http://grb.rssi.ru/GRB030329/
Detailed calibration and observations are continuing.
