Piccioni (Bologna University), A. Righini (Firenze\n  University) and I. Bruni (Bologna Astronomical Observatory) report:\n \n  We observed  the optical afterglow (Peterson & Price, GCN\n  1985) of GRB 030329 (Vanderspek et al., GCN 1997),\n  using the 152cm telescope + BFOSC of the Astronomical Observatory in\n  Loiano (Italy),\n \n  Seeing was  ~ 1.5\", but observing conditions were limited, due to\n  the low angular distance to the moon and the not perfect weather conditions.\n  We co-added the three exposures listed below:\n \n   UT start    exptime  filter\n  -----------------------------\n  Apr. 13.8783  300s     Rc\n  Apr. 13.8824  300s     Rc\n  Apr. 13.8865  300s     Rc\n \n  and used the following stars in Henden's photometric calibration\n  (GCN2082):\n \n  RA= 161.174977  DEC= 21.542124\n  RA= 161.158874  DEC= 21.562989\n  RA= 161.162639  DEC= 21.516308\n  RA= 161.166023  DEC= 21.570694\n \n  We obtain a preliminary magnitude Rc = 18.66 +/- 0.11.\n  This message may be cited.",
