Smith (LJMU) on behalf of a\nlarger collaboration report:\n\nOn 2008 August 05 (10:12:35 UT) we began observing the field of GRB 080805\n(Pagani et al. GCN Circ. 8059) with the Faulkes Telescope South using\nthe R and i' filters.\n\nIn our coadded i' frame we marginally detect the optical afterglow\n(Kruehler et al. GCN Circ. 8060; de Ugarte Postigo et al. GCN Circ. 8061):\n\nTelescope   Filter  T_mid[hr]   Exposure[s]      Mag\n-----------------------------------------------------------\nFTS         i'         5.410       6x300       22.5 +/- 0.4\n-----------------------------------------------------------\n\nThe calibration was performed using the I magnitudes of several\nUSNOB-1 catalogue field objects.\nFrom the comparison with the value reported by GROND\n(Kruehler et al. GCN Circ. 8060) we estimate an average\npower-law decay index of ~0.7, consistent with that inferred\nin the R band (de Ugarte Postigo et al. GCN Circ. 8061).",
