TITLE: GCN CIRCULAR NUMBER: 14353 SUBJECT: Swift/XRT observation of GRB 130327B DATE: 13/03/29 13:16:30 GMT FROM: Hans Krimm at NASA-GSFC H. A. Krimm (CRESST/GSFC/USRA) and V. Mangano (INAF-IASFPA) for the Swift team: We have analysed 7.9 ks of XRT data for the AGILE/Konus/Fermi-detected burst: GRB 130327B (Longo et al, GCN 14344; Chaplin & Fitzpatrick, GCN 14346; Ohno et al, GCN 14347; Golenetskii et al, GCN 14348), from 110.1 ks to 128.6 ks after the Fermi/GBM trigger. The data are entirely in Photon Counting (PC) mode. An X-ray source is detected within the Fermi/LAT error circle. The refined XRT position is RA, Dec = 217.87488, -69.40345 which is equivalent to: RA (J2000): 14 31 29.97 Dec(J2000): -69 24 12.4 with an uncertainty of 4.1 arcsec (radius, 90% confidence). This position is 459 arcsec from the Fermi/LAT position. We cannot determine at the present time whether the source is fading. The count rate level is 4 x 10^-3 counts/s. Further Swift observations have been scheduled.
