GCN Circular 3463
M. Capalbi, M. Perri, P. Giommi (ASDC), J. A. Kennea, D. N. Burrows, (PSU), F. Marshall, N. Gehrels (NASA/GSFC) report on behalf of the Swift XRT team: We have analyzed the Swift XRT data from the INTEGRAL XRF 050522 (Gotz et al., GCN 3446). Analysis of 10077 seconds of Photon Counting mode data reveals a weak uncataloged X-ray source within the INTEGRAL error circle. The probability that the source is a fluctuation of the background is about 5.6E-5. The source coordinates are: RA(J2000) = 13 20 35.0 Dec(J2000) = +24 47 18 We estimate an uncertainty of 6 arcseconds radius (90% containment). This source is located 12 arcseconds from the INTEGRAL position reported in GCN 3446. The count rate in the 0.3-10 keV band is 1.6E-03+/-0.5E-03. We cannot yet determine whether this X-ray source is fading. We confirm that the X-ray source outside the INTEGRAL error circle reported previously on the basis of a preliminary analysis (Kennea et al., GCN 3452) is not fading and is no longer considered an afterglow candidate. Further XRT observations are planned.
