TITLE: GCN CIRCULAR NUMBER: 26277 SUBJECT: GRB 191122A: Swift/UVOT Upper Limits DATE: 19/11/23 01:05:16 GMT FROM: Paul Kuin at MSSL N. P. M. Kuin (UCL-MSSL) and B. Sbarufatti (PSU) report on behalf of the Swift/UVOT team: The Swift/UVOT began settled observations of the field of GRB 191122A 104 s after the BAT trigger (Sbarufatti et al., GCN Circ. 26269). No optical afterglow consistent with the XRT position (Evans GCN Circ. 26270,26272) 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 104 253 147 >21.1 u_FC 316 566 246 >20.4 white 104 11801 1305 >22.0 v 647 6097 432 >20.2 b 572 10938 1121 >21.9 u 316 6696 642 >20.5 w1 696 6508 413 >20.1 m2 846 6303 413 >21.2 w2 797 5893 413 >20.1 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).
