Gehrels (NASA/GSFC) report on behalf of the Swift XRT team:\n\nWe have analyzed the Swift XRT data from the INTEGRAL XRF 050522\n(Gotz et al., GCN 3446).  Analysis of 10077 seconds of Photon Counting mode \ndata reveals a weak uncataloged X-ray source within the INTEGRAL error circle.\nThe probability that the source is a fluctuation of the background is about \n5.6E-5.\n\nThe source coordinates are:\n\nRA(J2000) = 13 20 35.0\nDec(J2000) = +24 47 18\n\nWe estimate an uncertainty of 6 arcseconds radius (90% containment).\nThis source is located 12 arcseconds from the INTEGRAL position reported\nin GCN 3446.  The count rate in the 0.3-10 keV band is  1.6E-03+/-0.5E-03.\nWe cannot yet determine whether this X-ray source is fading.\n\nWe confirm that the X-ray source outside the INTEGRAL error circle\nreported previously on the basis of a preliminary analysis (Kennea et al.,\nGCN 3452) is not fading and is no longer considered an afterglow candidate.\n\nFurther XRT observations are planned.",
