GRB 221016A: Swift/UVOT Detection
Abstract
The Swift/UVOT began settled observations of the field of GRB 221016A 97 s after the BAT trigger (Page et al., GCN Circ. 32774). A source consistent with the enhanced XRT position (Goad et al. GCN Circ. 32776) 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 early exposures are: Filter T_start(s) T_stop(s) Exp(s) Mag white 97 247 147 20.20 +/- 0.23 b 3736 3861 123 >19.8 u 309 349 39 >18.8 The magnitudes in the table are not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.026 in the direction of the burst (Schlegel et al. 1998).
