Circ. 11716), gathering 4.9 ks of data between T0+250ks and\nT0+275 ks. Source B reported by Nakahira (GCN Circ. 11725)\nhas faded to a level of  0.005 +/- 0.001 count/sec, with a power-law decay\nindex of alpha= -1.4 +/- 0.3. This source is thus confirmed as the X-ray\nafterglow of GRB 110213B.\n\n\nThe results of the XRT-team automatic analysis are available at\nhttp://www.swift.ac.uk/xrt_products/00020157.\n\nThis circular is an official product of the Swift-XRT team.",
