TITLE: GCN CIRCULAR NUMBER: 11738 SUBJECT: Swift/UVOT observations of GRB110210a. DATE: 11/02/16 13:25:39 GMT FROM: Massimiliano de Pasquale at MSSL-UCL M. De Pasquale (MSSL-UCL) and V. D'Elia (ASDC) on behalf of the Swift/UVOT team report: The Swift/UVOT began settled observations of the field of GRB 110210A 144 s after the BAT trigger (D'Elia et al., GCN Circ. 11687). No optical afterglow consistent with the enhanced XRT position (Goad et al., GCN Circ. 11689) is detected in the initial UVOT finding charts nor in the summed exposures in all filters. (Poole et al. 2008, MNRAS, 383, 627) for the finding chart (FC) exposures and subsequent exposures are: Filter T_start(s) T_stop(s) Exp(s) Mag white_FC 144 294 147 >20.1 u_FC 302 552 246 >19.4 white 144 7686 746 >21.0 v 633 13497 1238 >19.7 b 558 7481 526 >20.1 u 302 7276 756 >19.9 w1 682 7072 294 >19.5 m2 660 18180 839 >20.6 w2 608 12588 1291 >21.0 The values quoted above are not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.06 in the direction of the burst (Schlegel et al. 1998).
