Gehrels (NASA/GSFC) report on behalf of \nthe Swift-XRT team:\n\nSwift-XRT performed a second observation of the IPN-discovered burst GRB \n060928 on 2006-10-07 starting at 01:17 (9 days after the trigger).\n\nIn a 10 ks observation, we no longer detect the source reported in GCN\nCirc. 5686 (Page et al.) Thus, we confirm that this source [previously\nreported to have a position of RA,Dec 08 30 29.90, -42 44 58.5 (J2000),\nestimated uncertainty 6 arcsec radius] has faded from view. \n\nDuring this second observation, the 3-sigma upper limit on the count rate\nis about 3e-3 count s^-1, corresponding to an observed (unabsorbed) flux\nof 2.1e-13 (4.9e-13) erg cm^-2 s^-1. Since the source has faded over time,\nit is, indeed, believed to be the X-ray afterglow of GRB 060928.\n\nThis circular is an official product of the Swift-XRT team.",
