GCN Circ. 8169) with the Liverpool Telescope\nusing the SDSS i filter.\n\nWe clearly detect the optical afterglow candidate reported by de\nUgarte Postigo et al. (GCN Circ. 8172) and Korotkiy et al.\n(GCN Circ. 8173). We found the following magnitudes:\n\nTelescope   Filter  T_mid[hr]   Exposure[s]      Mag\n-------------------------------------------------------------\nLT          i'         2.59       6x300        21.32 +/- 0.07\nLT          i'         4.08       6x300        21.52 +/- 0.11\n-------------------------------------------------------------\n\nThe calibration was performed using the I magnitude of the following\nnearby USNOB1 catalogue star: 05:47:14.30, +51:15:32.8, using I=14.77.",
