Sunyaev (IKI),\nreport:\n\n    We have observed the error box of GRB 050408(GCN 3189 and  GCN 3191) \nwith TFOSC (the imaging and spectroscopic camera of the TUBITAK National \nObservatory, Turkey) attached to the Russian-Turkish 1.5-m telescope \n(Bakyrlytepe, Turkey). We made series of 30s and 60s  exposures in Rc, \nstarting at 18:46 UT. We have found the OT candidate indicated in GCN 3193 \ngetting fainter with a spectral index of -0.63. We have determined its \npostion and magnitudes using USNO-B1. The position and the preliminary R \nphotometry are as follows:\n\nRA: 12:02:17.31  Dec: +10:51:9.4 (+/- 0.1 arcsec)(2000)\n\nT-T0(hours)        Rc\n3.7            20.94 +/- 0.1\n4.4            21.05\n5.4            21.17\n6.7            21.31\n8.3            21.50\n\nThe reductions are in progress.\nThis message may be cited.",
