GCN Circ. 9846) \non 2009 September 9th and 13th, 13 and 17 days after the trigger, \nrespectively. The XRT gathered 14 ks of Photon Counting mode data in this \ntime.\n\nThe source reported by Evans & Oates (GCN Circ. 9847) is not detected,\nwith a 3-sigma upper limit of 8.6 x 10^-4 count s^-1, significantly below\nthe level of the previous detection. We thus conclude that this source\nwas the afterglow of GRB 090827.\n\nThis circular is an official product of the Swift-XRT team.",
