GCN Circular 3514
J. L. Racusin, D. N. Burrows, J. A. Kennea, A. Retter (PSU), C. Pagani (INAF-OAB), A. Wells (U. Leicester), N. Gehrels (NASA/GSFC) report on behalf of the Swift XRT team: The Swift BAT detected GRB 050603 at 06:29:05.2 UT on June 3rd 2005 (GCN 3509, Retter et al.). The Swift observatory did not slew promptly because automated slewing was not enabled due to engineering tests. The XRT began taking data at 17:19:27 UT, approximately 11 hours after the trigger. In a preliminary data analysis we detect an uncataloged X-ray source located at: RA(J2000) = 2:39:56.6, Dec(J2000) = -25:10:52.5 We estimate an uncertainty of 8 arcseconds radius (90% containment). This position is 51 arcseconds from the BAT refined position reported by Fenimore et al. (GCN 3512), 5.6 arseconds from the optical afterglow candidate reported by Berger et al. (GCN 3511), and 4.5 arcseconds from the radio afterglow candidate reported by Cameron et al. (GCN 3513). Observations are still underway and further ground analysis will be performed to determine if this X-ray source is fading.
