GCN Circular 9707
K.L. Page (U. Leicester) reports on behalf of the Swift-XRT team: Following a delay caused by an Earth-limb constraint, the Swift-XRT started observing GRB 090726 about 49 minutes after the trigger, at 23:36:32 UT. The XRT initially centroided on a cosmic ray; however, using promptly downlinked data we find an uncatalogued X-ray source with an enhanced position: RA, Dec = 248.6788, 72.8843 (degrees) which is equivalent to: RA (J2000.0) = 16 34 42.90 DEC (J2000.0) = +72 53 03.3 with an uncertainty of 2.2 arcsec (radius, 90% containment). This location is 156.1 arcseconds from the BAT onboard position, inside the BAT error circle. It is not possible to determine whether the source is fading at this time. This circular is an official product of the Swift-XRT team.
