TITLE: GCN CIRCULAR NUMBER: 19696 SUBJECT: GRB 160712A: Swift/UVOT Upper Limits DATE: 16/07/13 18:19:55 GMT FROM: Lea Hagen at PSU L. M. Z. Hagen (PSU) reports on behalf of the Swift/UVOT team: The Swift/UVOT began settled observations of the field of GRB 160712A 3998 s after the BAT trigger (Hagen et al., GCN Circ. 19684). No optical afterglow consistent with the XRT position (Beardmore et al., GCN Circ. 19690) or the possible optical afterglow candidate (Kruehler et al., GCN Circ. 19693; Troja et al., GCN Circ. 19695) 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 exposures are: Filter T_start(s) T_stop(s) Exp(s) Mag white 3998 4148 147 >20.47 v 4154 4354 196 >19.04 b 4974 5027 52 >19.17 u 4769 4969 196 >19.66 uvw1 4564 4764 196 >19.58 uvm2 4359 4559 196 >19.52 The magnitudes in the table are not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.08 in the direction of the burst (Schlegel et al. 1998).
