GCN Circ. 8944) for 5.8 ks, from T0+67 ks to T0+81 ks. The \ndata were entirely in PC mode.\n\nA single, faint source is found in the BATSS error circle, with a position \nRA,Dec = 231.2083, -6.9682 which is equivalent to:\n\nRA (J2000)  = 15 24 49.99\nDec (J2000) = -06 58 05.6\n\nwith an uncertainty of 4.0 arcsec (radius, 90% confidence).\n\nWe currently have only 16 counts from this source, at a count rate of 3.5 \n(+/- 0.9) e-3 counts s-1, and are unable to ascertain whether it is \nfading.\n\nFurther observations, to verify the nature of this source, are planned.\n\nThis circular is an official product of the Swift-XRT team.",
