TITLE: GCN CIRCULAR NUMBER: 17126 SUBJECT: GRB 141130A: Swift/UVOT Detection DATE: 14/12/01 13:26:52 GMT FROM: Paul Kuin at MSSL S. R. Oates (IAA-CSIC/UCL-MSSL) and A. Vargas (PSU) report on behalf of the Swift/UVOT team: The Swift/UVOT began settled observations of the field of GRB 141130A 95 s after the BAT trigger (Vargas et al., GCN Circ. 17120). A source consistent with the XRT position (Goad et al. GCN Circ. 17123) is detected in the initial UVOT exposures. The preliminary UVOT position is: RA (J2000) = 14:51:17.23 = 222.82181 (deg.) Dec (J2000) = +47:19:07.3 = 47.31870 (deg.) with an estimated uncertainty of 0.45 arc sec. (radius, 90% confidence). 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 95 244 147 18.71 +/- 0.06 v 636 655 19 >17.8 b 562 753 39 >20.1 u 306 556 246 18.85 +/- 0.13 w1 684 704 19 >18.7 w2 611 798 34 >19.0 The magnitudes in the table are not corrected for the Galactic extinction due to the reddening of E(B-V) = 0.02 in the direction of the burst (Schlegel et al. 1998).
