| 英文摘要 | The Swift/UVOT began settled observations of the field of GRB 191011A 78 s after the BAT trigger (Laha et al., GCN Circ. 25988). A source consistent with the XRT position (Evans et al. GCN Circ. 25995) is detected in the initial UVOT exposures. This GRB was also detected by Fermi/GBM (GCN Circ. 25987,26000) and Insight-HXMT-HE(Yi et al, GCN Cir. 25997). A redshift was reported using the VLT/Xshooter (Kahn et al, GCN Circ.25991), while the optical afterglow was reported from Master (Lipunov et al, GCN Circ. 25990; GROND (Nicuesa Guelbenzu et al., GCN Circ. 25992). The preliminary UVOT position is: RA (J2000) = 02:58:54.79 = 44.72829 (deg.) Dec (J2000) = -27:50:43.4 = -27.84540 (deg.) with an estimated uncertainty of 0.73 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 78 228 147 20.27 +/- 0.16 v 620 11672 1211 >20.2 b 545 7080 510 21.03 +/- 0.27 u 290 6875 697 20.86 +/- 0.27 w1 670 6670 510 >20.3 m2 1073 12198 767 >21.1 w2 1024 7491 432 >20.9 The afterglow is seen to be nearly constant in the white filter until about 1000s, whereafter a decay is observed. 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). |
