TITLE: GCN CIRCULAR NUMBER: 15851 SUBJECT: GRB 140211A: Swift-XRT and UVOT observations DATE: 14/02/16 18:51:10 GMT FROM: Valerio D'Elia at ASDC M. De Pasquale (MSSL-UCL), V. D'Elia (ASDC), L. Izzo (Uroma/ICRA) and J. R. Cummings (NASA/UMBC) report on behalf of the Swift-XRT team: We have analysed 2.7 ks of XRT data for GRB 140211A (Cummings  et al. GCN Circ. 15816),  from 298.7 ks to 385.2 ks after the BAT trigger. The data are entirely in Photon Counting (PC) mode. The refined XRT position is RA, Dec = 124.22331, +20.2432 which is equivalent to: RA (J2000): 08 16 53.59 Dec(J2000): +20 14 35.5 with an uncertainty of 4.4 arcsec (radius, 90% confidence). We cannot determine at the present time whether the source is fading. The results of the XRT-team automatic analysis are available at http://www.swift.ac.uk/xrt_products/00586289. UVOT performed observations of GRB140211A in UVM2 and UVW1. At the position of the XRT source, no counterpart is detected in these filters in summed exposures. Preliminary 3-sigma upper limits using the UVOT photometric system (Breeveld et al 2011, AIP Conf. Proc. 1358, 373) are Filter     T_start (s)     T_Stop (s)     Exp (s)     Mag um2       298690        298860        167        >19.5 uw1        338330       385245      2438        >21.3 No correction has been made for extinction corresponding to E(B-V)=0.04 (Schlegel et al 1998).
