Lipkin (Wise observatory, TAU) report:\n\nWe have observed the error box of the of the Swift trigger 149118\n(Cummings et al. 2005, GCN 3766; designated as GRB 050805a by Lipunov et\nal. GCN 3767), using the Wise observatory 1m telescope + Tek CCD camera,\nstarting at 2005, Aug 05th, 21:50 UTC.\nComparing a 300 sec R-band image which we obtained (mid exposure time\n0.15851 days after the Swift-BAT trigger) to the POSS2 R-band image,\nwe did not detect any new source in the 2\" error circle of the optical\ntransient that was reported by Lipunov et al. (GCN 3767).\nThe limiting magnitude of our image was R=19.5.\n\nIf we understood correctly the message of Lipunov et al., then\nour observations took place 2.637 hrs after theirs.\nIf Lipunov et al. indeed detected the OT, and further\nassuming a power-law decay, this time difference would imply a\ndecay-rate index that is larger than 2.08.\n\nWe note that according to GCN 3766, GRB050805a\nis probably not a real GRB.",
