Cummings (NASA/UMBC) report on behalf of \nthe Swift-XRT team:\n\nAdditional Swift-XRT observations have been performed of the possible \nX-ray afterglow of GRB 070917 (Evans et al., GCN Circ. 6796). Between \n~3.5e4 and 3.5e5 seconds after the burst, the source has faded following a \npower-law decay slope of alpha = 1.1 +/- 0.3, confirming that it is, \nindeed, the afterglow. Using ~14 ks of data, we find a refined position of \nRA, Dec = 293.91897, 2.41104 degrees, which is equivalent to:\n\nRA(J2000) =  19 35 40.55\nDec(J2000)= +02 24 39.8\n\nwith an estimated uncertainty of 6.0 arcsec (radius, 90% containment \nincluding boresight uncertainty). This source is 0.7\" from the optical \ncounterpart discussed by Cenko (GCN Circ. 6800) and Fynbo et al. (GCN Circ \n6803).\n\nThis circular is an official product of the Swift-XRT team.",
