TITLE: GCN CIRCULAR NUMBER: 11406 SUBJECT: GRB 101114A: Swift-XRT candidate afterglow detection and analysis DATE: 10/11/15 09:30:57 GMT FROM: Phil Evans at U of Leicester P.A. Evans (U. Leicester) reports on behalf of the Swift-XRT team: We have analysed 7.9 ks of XRT data for GRB 101114A (Sakamoto et al. et al. GCN Circ. 11405), from 73.3 ks to 91.1 ks after the BAT trigger. The data are entirely in Photon Counting (PC) mode. An uncatalogued X-ray source is detected inside the BAT error circle; the source shows weak (~1-sigma) evidence of fading in this observation. Using 1631 s of PC mode data and 1 UVOT image, we find an enhanced XRT position (using the XRT-UVOT alignment and matching UVOT field sources to the USNO-B1 catalogue): RA, Dec = 303.21110, +14.03270 which is equivalent to: RA (J2000): 20h 12m 50.67s Dec(J2000): +14d 01' 57.6" with an uncertainty of 2.8 arcsec (radius, 90% confidence). This is 64 arcsec from the BAT position of Sakamoto et al. (GCN Circ. 11405) A spectrum formed from the PC mode data can be fitted with an absorbed power-law with a photon spectral index of 2.1 (+1.1, -0.6). The best-fitting absorption column is 1.6 (+2.5, -0.3) x 10^21 cm^-2, consistent with the Galactic value of 1.2 x 10^21 cm^-2 (Kalberla et al. 2005). The counts to observed (unabsorbed) 0.3-10 keV flux conversion factor deduced from this spectrum is 3.7 x 10^-11 (5.5 x 10^-11) erg cm^-2 count^-1.
