Marshall (GSFC) report on behalf of the\nSwift-XRT team.\n\nWe have analyzed the first orbit of XRT data of the Swift\nobservation of GRB 071011 (Marshall et al., GCN 6882), started\nat 13:28:40 UT.\nWe have a 1600 sec exposure in PC mode. We detect a single\nuncatalogued bright source within the XRT field of view,\nacross an hot column, at position\nRA, Dec= 8.3887, +61.1325 deg which is\n\n   RA(J2000)=   0h 33m 33.30s\n   Dec(J2000)=  +61d 07' 57.3\"\n\nwith an uncertainty of 4.4 arcsec (90% containment radius). This\nis 11 arcsec from the BAT refined  position (Sakamoto et al,\nGCN 6889). We remark that the new BAT error circle excludes the\noptical afterglow candidate reported by Perley et al. (GCN 6883).\nA quick look to the XRT light curve gives a flat behavior at the\nlevel of 0.3 counts/sec. We wait for more data to improve our\nanalysis.",
