Siegel (PSU)\nreport on behalf of the Swift/UVOT team:\n\nThe Swift/UVOT began settled observations of the field of GRB 151114A\n95 s after the BAT trigger (Siegel et al., GCN Circ. 18599).\nA source consistent with the XRT position\n(Siegel et al. GCN Circ. 18599)\nis detected in the initial UVOT exposures.\n\nThe preliminary UVOT position is:\n    RA  (J2000) =  08:03:46.33 = 120.94306 (deg.)\n    Dec (J2000) = -61:01:40.0  = -61.02779 (deg.)\nwith an estimated uncertainty of 0.45 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.
