Guidorzi (INAF-OAB)\non behalf of a larger collaboration reports:\n\nThe robotic 2m Faulkes Telescope North located in Hawaii observed\nthe field of the GRB 081007 (Baumgartner et al. GCN 8330) starting\nautomatically as soon as the target rose above the observable horizon\nabout 17 minutes after the GRB time.\n\nA fading optical source is detected at the XRT position reported by\n(Baumgartner et al. GCN 8330). Over the period from 0.2 - 1 hour after the\nburst, the OT is seen to fade in both R and I with a flux power law slope\nof -0.7.\n\nFilter  Mag\t\tT_mid[min]\n-----------------------------\nR       17.9 +/- 0.4\t17.50\nR       18.6 +/- 0.4\t46.66\n\nI       17.1 +/- 0.4\t21.55\nI       17.6 +/- 0.4\t39.38\n-----------------------------\n\n\nThe calibration was performed using the R2 and I magnitudes of the\nUSNOB-1 catalogue field star at 22:39:43 -40:10:15.3 J2000.
