GCN Circular 13484
N. P. M. Kuin (MSSL-UCL), F. Marshall (NASA/GSFC), and C. J. Saxton (UCL-MSSL) report on behalf of the Swift/UVOT team: The Swift/UVOT began settled observations of the field of GRB 120714B 129 s after the BAT trigger (Saxton et al., GCN Circ. 13471). The UVOT source candidate reported by Marshall and Saxton (GCN Circ. No. 13473) is found to decay. The preliminary UVOT position is RA, Dec (J2000) = (355.40864,-46.18387), or in sexagesimal coordinates: RA = 23h41m38.1s Dec = -46d11'02" with 90% confidence error radius of 0.58". Preliminary detections and 3-sigma upper limits using the UVOT photometric system (Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) for the early exposures are: Filter T_start(s) T_stop(s) Exp(s) Mag white 129 165 35 18.40 +/- 0.20 white 10034 10184 147 >20.8 b 10195 11102 885 >21.5 The magnitudes in the table are not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.01 in the direction of the burst (Schlegel et al. 1998).
