TITLE: GCN CIRCULAR NUMBER: 32932 SUBJECT: GRB 221110A: Swift/UVOT Detection and Corrected UVOT Position DATE: 22/11/11 04:27:28 GMT FROM: Sam LaPorte at PSU GRB 221110A: Swift/UVOT Detection and Corrected UVOT Position S. J. LaPorte (PSU) and M. Williams (PSU) report on behalf of the Swift/UVOT team: The Swift/UVOT began settled observations of the field of GRB 221110A 83 s after the BAT trigger (Williams et al., GCN Circ. 32925). A fading source is detected at RA (J2000) = 01:56:23.72 = 29.09882 Dec (J2000): = -27:17:45.09 = -27.29586 which is consistent with the XRT position (Evans et al. GCN Circ. 32929). The UVOT position reported in the initial detection circular (Williams et al., GCN Circ. 32925) was incorrect, and differs from the updated position presented here by 8.45 arcsec. We apologize for any inconvenience this discrepancy may cause. 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 b 3773 3973 196 >19.91 m2 4593 4793 196 >19.35 u 326 439 110 >19.33 v 4357 4557 197 >19.5 w1 4798 4998 196 >19.48 w2 4184 4383 196 >19.55 white_FC 114 264 147 18.68+-0.08 white 3978 4178 196 >20.66 The magnitudes in the table are not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.013 in the direction of the burst (Schlegel et al. 1998).
