Kuin (MSSL-UCL) reports on behalf of the Swift/UVOT team:\n\nThe Swift/UVOT began settled observations of the field of GRB 121201A\n120 s after the BAT trigger (Yershov et al., GCN Circ. 14025).\nA source consistent with the XRT position is detected in the\ninitial UVOT exposures.\n\nThe preliminary UVOT position is:\n    RA  (J2000) =  00:53:52.16 =  13.46732 (deg.)\n    Dec (J2000) = -42:56:34.5  = -42.94292 (deg.)\nwith an estimated uncertainty of 0.62 arc sec. (radius, 90% confidence).\n\nPreliminary detections and 3-sigma upper limits using the UVOT\nphotometric system\n(Breeveld et al. 2011, AIP Conf.
