TITLE: GCN CIRCULAR NUMBER: 14041 SUBJECT: GRB 121202A: Swift/UVOT Upper Limits DATE: 12/12/02 19:50:51 GMT FROM: Samantha Oates at MSSL S. R. Oates (MSSL-UCL) reports on behalf of the Swift/UVOT team: The Swift/UVOT began settled observations of the field of GRB 121202A 2828 s after the BAT trigger (Oates et al., GCN Circ. 14032). No optical afterglow consistent with the XRT position (Evans et al. GCN Circ. 14038) is detected in the initial UVOT exposures. Preliminary 3-sigma upper limits using the UVOT photometric system (Breeveld et al. 2011, AIP Conf. Proc. 1358, 373) for the first finding chart (FC) exposure and subsequent exposures are: Filter T_start(s) T_stop(s) Exp(s) Mag white_FC 2828 2978 147 >20.3 white 2828 5033 541 >21.0 v 3808 16147 1205 >20.2 b 3192 22680 1059 >20.9 u 2987 28451 2637 >21.2 w1 4218 27811 2853 >21.4 m2 4012 26905 2713 >21.5 w2 3603 31934 1549 >21.2 The magnitudes in the table are not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.05 in the direction of the burst (Schlegel et al. 1998).
