Saxton (UCL-MSSL)\nreport on behalf of the Swift/UVOT team:\n\nThe Swift/UVOT began settled observations of the field of GRB 120714B\n129 s after the BAT trigger (Saxton et al., GCN Circ. 13471).\nThe UVOT source candidate reported by Marshall and Saxton\n(GCN Circ. No.  13473) is found to decay.\n\nThe preliminary UVOT position is RA, Dec (J2000) = (355.40864,-46.18387),\nor in sexagesimal coordinates:\n\nRA = 23h41m38.1s\nDec = -46d11'02\"\n\nwith 90% confidence error radius of 0.58\".\n\nPreliminary detections and 3-sigma upper limits using the UVOT\nphotometric system\n(Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) for the early exposures are:\n\nFilter         T_start(s)   T_stop(s)      Exp(s)           Mag\n\nwhite              129          165           35         18.40 +/- 0.20\nwhite            10034        10184          147        >20.8\nb                10195        11102          885        >21.5\n\nThe magnitudes in the table are not corrected for the Galactic extinction\ndue to the reddening of E(B-V) = 0.01 in the direction of the burst\n(Schlegel et al. 1998).",
