GRB 230510A: Swift/UVOT Observations
Abstract
The Swift/UVOT began settled observations of the field of GRB 230510A 72 s after the BAT trigger (Eyles-Ferris et al., GCN Circ. 33752). A source consistent with the XRT position (Evans et al., GCN Circ. 33756) is detected in the initial UVOT exposures. Preliminary detections and 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 wh_FC 72 222 150 18.90+/-0.10 u_FC 284 318 34 18.09+/-0.32 wh 4413 4613 200 19.33+/-0.11 v 4824 5024 200 18.97+/-0.32 b 4209 5690 241 19.31+/-0.17 u 5439 5638 199 19.10+/-0.24 w1 5234 5434 200 19.30+/-0.34 m2 5029 5228 199 >19.21 w2 4619 4819 200 >19.45 The magnitudes in the table are not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.144 in the direction of the burst (Schlegel et al. 1998).
