Sharapov (UBAI),\nA.Pozanenko (IKI),\nV.Rumyantsev (CrAO),  G.Beskin (SAO) report:\n\nWe have observed the filed of error box of  GRB041006 (HETE #3570, M.\nGalassi, et al. GCN 2770) starting Oct.6 15:49 (UT) with  1.5m telescope of\nMt.Maidanak High-altitude Observatory. Several BVRI images were taken\nbetween 15:49 and 16:51. We confirm a fading source found by G. Da Costa et\nal. (GCN 2765). Preliminary reduction of the data against the USNO-A2.0\ncatalog yield the following OT magnitudes in R\n\nUT      exposure mag   err\n15:49   180 s    18.7 (0.09)\n16:46   300 s    19.1 (0.10)\n\nThe magnitudes assume a temporal decay index about 1.5 which is stepper than\nfound by P.A. Price, et al. (GCN 2771) and may indicate a brake of a light\ncurve of the OT.\n\nThis message may be cited.",
