On October 7, 2004 in clear sky conditions (seeing 2") we obtained
two R-band images (1200 sec X 2) of the OT of GRB 041006 (=HETE 3570)
reported by Da Costa, Noel and Price (GCN 2765) with the 152 cm telescope
in Loiano.We co-added the two exposures and used the following stars
in Henden's photometric calibration (GCN 2801):
RA Decl.
13.6373 1.221278
13.708797 1.202692
13.783485 1.302545
We find the following magnitude for the OT:
R = 22.22 +/- 0.13 at UT 22:40 (mean value).
